Introduction
In advance, the game was changed with the addition of the Choice Band. This revolutionary item allowed a user to attack with 1.5Xs the normal power but restricted the user to only one attack until it is recalled. In D/P, Game Freak decided to expand on this and add Choice Specs and Choice Scarf to the mix. So here is a quick recap:
Choice Band: increases pokemon's physical attack power of selected move by 50% until it is recalled.
Choice Specs: increases pokemon's special attack power of selected move by 50% until it is recalled.
Choice Scarf: increases pokemon's speed by 50% and restricts usage to one move until it is recalled.
Discussion
So now that the formailities are out of the way, I am going to open this discussion to talk about Choice Items. In short, I think the metagame is going about using Choice Items completely the wrong way, and that is evident in all the RMTs and Peer Edits I have seen as of late. So this is mainly a reflection on my personal experiences and my theories on how people should be using Choice Items. Feel free to discuss, agree, disagree, etc.. after all this is a discussion thread.
Choice Effectiveness
So basically, I can't make an such an audatious claim without supporting it, so I have to offer suggestions and reasons why I think Choice items are misused. So this section will explain some reasoning behind my madness.
Choice Band / Specs vs. Scarf: In my opinion Choice Band / Specs are much safer and more effective in the current Metagame than Choice Scarf. In fact, Choice Scarf may be the reason taht Choice items are overused in first place. Why is Choice Band / Specs more effective? Easy! If you use them correctly, they take nice chunks out of an opposing team and while at the same time leaving you less vulnerable to set-up then Choice Scarf.
What makes a good user of Choice Specs / Band???
- Power - Pretty simple and straightforward. You don't want to waste your time slapping a Choice Band on a pokemon with base 70 Attack now do you??? Another VERY important overlooked think to note about power is the base power of the moves, which I will discuss in depth further down. Gyarados has an excellent attack score but is rather mediocre as a Choice user because of its weak base power STAB attack, among other things.
- Neutral Coverage - This is THE MOST frustrating and important point I can make in this entire thread. Lately, I see many users submitting sets that concentrate on hitting targets Super Effectively. However, that is a terrible misconception about Choice Items. In fact, the reverse is true. The key to using Choice Specs / Band is to focus on your neutral coverage, regardless of the type chart. Why? It is more important.. that simple. Because you are boosting damage, super effective type coverage should be of little concern, and certainly not be first thing you think about when designing a Choice Set for your team. Realistically, you should try to choose a pokemon that can acheive nearly perfect coverage in just two moves. You should never have to use the fourth option, and will rarely use the third option in most cases. Therefore, omit any unneccessary moves that are disgned to hit specific pokemon Super Effective, rather than concentration on your own coverage. For example, say you choose Choice Specs Heatran, and you opt to put Hidden Power Electric on it to deter Gyarados switch ins.. Bad idea. Why? A Timid Choice Specs Heatran will hit offensive Gyarados 44-53%, and bulky Gyarados for 37-44%. That is the whole nature of Choice Items... to fire off your most powerful attack to keep the other team off balance. Therefore, listen carefully to what I am about to say: If you have to use Hidden Power on a Choice Specs user to acheive decent neutral coverage, it probably isn't a good candidate fore Choice Specs to begin with. Hidden Power is a mistakingly overused move, and its horrid power is undesirable. I will explain when I get into set details.
- Accessibility: This is something many of you already now and consciously think about when assigning Choice Items to specific pokemon. How easy is it to get this Choice user in???? Picking a Choice user that has multiple attempts to get in will be most beneficial to your team in the long run, and allow you to punch more holes in the opponents team. So things here to consider are weakness / susceptibility to entrance hazards, immunities to attacks or status, and resistances.
- The "Uncertainty Factor:" This is something I sort of came up with myself that makes certain Choice Users especially good. The uncertainty factor is more of a bonus than anything, but does distinguish a few Choice candidates from others. So what I mean by this is a pokemon thats entry into battle creates difficult decisions for the opponent. Rather than just thinking about who to switch to, they now have to think about "Do I switch? or do I stay in?" Yes, I'm talking about Pursuiters like Tyranitar, U-turners like Scizor and Flygon, and pokemon with dry Baton Pass like Jolteon. Their appearance in battle can really put an opponent in a tight spot.
So, with all that being said, who are some good examples of Choice Specs / Band candidates? I'll start at the top. In my opinion this are the most potent users of each, and why you should use them.
Each candidate will have a mini "report card" that I encourage you guys to think about when you select Choice Users.

Jolteon is a solid Choice Specs user. It is fast, powerful, and Thunderbolt + Shadow Ball hits everything except Magnezone for neutral damage in OU. It has many opportunities to get in on Electric moves and Thunder-waves. It also can get in on predicted stat-up moves, such as an Infernape Nasty Plot. It can even switch in on a Dragon Dancing Gyarados.

Monstrous. Tougher to get in but they will both fuck shit up. Dragonite has Fire Punch, which 2HKOs Skarmory and Bronzong but Salamence has to resort to weaker moves. The beauty of them is though, anything slower is going to get 2HKOed, and anything faster is going to get OHKOed, hence, good uncertainty.
Choice Scarf: The Double Edged- Sword
There is way too much Choice Scarf usage in the Metagame now. Period. Many people rely on the Choice Scarf for revenge killing, but fail to realize that if you use a Choice Scarf to revenge kill a faster sweeper, you become mere set-up fodder for the next sweeper. Therefore, there are several reasons that you should STRONGLY consider before slapping Choice Scarf Pokemon X, just to seal your Y weakness.
Conclusion
All in all, I hope you guys enjoyed my rant about Choice Items in the metagame. Many of you will disagree with my stances, my pokemon choices, and my sets... but this is a discussion thread so go ahead and tell me I suck or that I'm a genius. Anyway, discuss Choice Items, and I hope I opened a few of you up to some new ideas about how dangerous they can be for both teams.

Therefore, there are several reasons that you should STRONGLY consider before slapping Choice Scarf Pokemon X, just to seal your Y weakness.
- Power: Like the other Choice sets, a Choice Scarfer has to be extremely powerful, even moreso then things you slap a Band or Specs on. If it manages to revenge kill something, your opponent has to be weary of setting up, therefore you want pokemon with very strong moves and very high attack scores. That already narrows the list of potential Scarfers.
- Neutral type coverage: Again like before, neutrality is even more powerful for revenge killing. If you can use brute strength, you don't have to deal with this next parameter on this list.
- Consequences: A Choice Scarf user has to be able to keep your team out of a tight situation even after it completed its revenge kill. A Choice Scarfer with bad consequences is going to lose a lot of games for you, and allow your opponent to dictate the pace of the match. This effect is much more severe with Chocie Scarf than it is with Choice Band or Choice Specs, mainly because they are damage boosting, and those pokemon can still hit even resists hard. So basically, more stars on the report card means the less likely this pokemon is to fuck you over after.
So with all that being said, I can only think of five Choice Scarfers that I would ever use, and they seldom find their way onto any of my teams. Again, I promise you will be happier with your teams if you can find another way to deal with Dragon Dance or Agility Sweepers. Choice Scarf can save you from a Salamence sweep, but open you up to a Lucario sweep. This is especially common on teams that use offensive type resisting duos, which is very common. So here are my Scarfers:

I was a little skeptical of even posting Heracross, since he is pretty much the opposite of what you want to use in a Choice Scarfer. However, his main STAB is resisted by pokemon that can be handled with his other moves, and in the right hands he is an absolute beast. Really the only thing Heracross has going for it is the insane attack and base power moves. If your looking for a Choice Scarfer, Heracross is a solid force, just have some Gyarados / Mence coverage. The whacky EV spread gives you 309 HP, and enough speed to outrun Jolly Gyarados after a DD.
So those are the creame of the crop in Choice Scarfers. I kno I will receive hate mail saying "you suck, Heatran is great!" but again, don't ever use Hidden Power on Choice pokemon unless you really have to, even then.. you are better off picking something else to do the job.
