What's the difference between dying 100% of the time because of the too low base power of Rock Slide/Brick Break and dying 20% of the time because of the poor accuracy of Cross Chop/Stone Edge? If anything, run Earthquake, since it has similar coverage to Cross Chop and does not miss, and give him some team support for Ferrothorn.
Did you considered that Cross Chop also has a Tough Claws boost?After the boost from Tough Claws, Brick Break has 2.5 less power than Cross Chop. I'd trade breaking screens and perfect accuracy for 2.5 more power, 20% chance to miss, and an increased critical chance.
I'm not so sure these numbers are accurate. If tough claws boosts BP by 33%, it would effectively be a 1/3rd boost to BP, making 60 BP moves 80, 75 BP moves 100, and so on. Razor shell is 75x1.5x1.33 = 149.62All the moves that make contact and are boosted by Tough Claws:
Aerial Ace - 78
Brick Break - 97
Clamp - 67
Cut - 65
Cross Chop - 130
Dragon Claw - 104
Dig - 104
Facade - 91 (182 if burned)
False Swipe - 52
Fury Cutter - 52 to 208
Fury Swipes - 23 to 117
Giga Impact - 195
Poison Jab - 104
Power-Up-Punch - 52
Razor Shell - 145
Rock Smash - 52
Shadow Claw - 91
Skull Bash - 169
Slash - 91
X-Scissor - 104
I've found Adamant to be a little better than jolly because the extra power you get from adamant is doubled and grants you quite a few more OHKO's. The extra speed won't be helpful against powerful scarfers like terrakion, so you may just have to predict their action with a well-placed switch (a ghost type tank would be a great switch because terrakion will not appreciate a burn and will be forced to switch, possibly allowing you to set up).Honestly? I've been running this set the past couple of battles and it's sort of a double edged sword.

If it works, it WORKS. It's beautiful watching your opponent get swept and almost nothing they can do can stop it. Now to justify the spread, I choose Jolly mostly because the boost in power from Shell Smash makes Adamant kinda not worth in my opinion. Running more speed just feels like a better idea - just... I'd say ten minutes ago? I was able to outrun your standard Bellyjet Azumarill, stomach an Aqua Jet with plenty to spare and finish off the rest of his team (and for proof: http://pokemonshowdown.com/replay/ou-80522342).
In my humble (and not worth listening to) opinion, it seems like Barbacle may be a really good high use UU or low OU Pokemon. I feel his strengths lie more in UU more than OU, and I'll be doing more testing, but then again, what do I know?

A max iv max ev adamant barbaracle will have 470 speed after a shell smash, which outspeeds up to 93 base speed (with max iv's, ev's, and a speed boosting nature) scarfers. That is pretty damn fantastic, especially when it comes with a 678 attack stat and moves ranging in power from. Now consider the same barbaracle, but with a jolly nature: 516 speed (outspeeds up to 107 base speed scarfers, which is still awesome) and an attack stat of 618. So, the difference is 60 attack and 46 speed. It's all up to preference. I just think the extra power really helps against strong physical walls that might OHKO you while enduring your attack (tangrowth and chesnaught are the only two pokemon I can think of that can achieve this, although I haven't considered strong gyro ball users). Basically, the only thing that can revenge kill this barnacle after a shell smash is up would be a strong physical wall or a fast scarfer with a grass move. That said, a grass move is easily predictable, which is why a sap-sipper makes an excellent teammate (Goodra seems like a good one with a physical moveset and can soak up special hits, spread paralysis, phaze, etc.; sawsbuck is another good choice and can baton pass its boost or use swords dance on a potential switch, putting it at +3)
Talonflame is excellent set-up bait. That is why having something weak to flying on your team is a good idea. Breloom, Heracross, and Chesnaught are excellent teammates, acting as bait for talonflame while also covering Barbaracle's ground and grass weakness and, in the case of heracross, his fighting weakness. Chesnaught also makes an excellent physical wall that can damage infernape on its attempts to hit with fire punch (spikey shield) and rack up life orb damage if he holds lefties. You can add leech seed to heal up behind spikey shield as well. Last of all, I think Togekiss will be another excellent teammate because of the 4x resistance to fighting, resistance to dark, immunity to dragon and ground attacks, and excellent flying STAB with air slash that can deal with physical walls that switch in on barbaracle and try to OHKO (Tangrowth, Chesnaught, etc.)
with regard to the choice band set, it just doesn't seem fast enough without sticky web support. I don't much care for the choice items anyway. I think shell smash, while not an immediate buff, is better because you can use Barbaracle's excellent movepool and coverage to its fullest extent. For a choice set, I would have stone edge, earthquake, x-scissor, and either razor shell or dragon claw as the 4th move. Razor shell is powerful STAB that will hit anything that doesn't resist or absorb it like a truck. Dragon claw has good neutral coverage and will hit things that try to predict stone edge, cross chop, or razor shell (as is popular at the moment) such as dragalge, garchomp, flygon, and so on. Just my thoughts on the matter.
