Been mucking around on doubles for a bit and was wondering whether Assault Vest was viable on Rhyperior? Does it turn any OHKOs into 2KHOs? Or is he better running something like expert belt or liechi berry?
Assault Vest might be good for certain attacks (and paired with Solid Rock its not bad), but any attack that is 4x super effective will still likely OHKO.
252+ SpA Rotom-W Hydro Pump vs. 252 HP / 252+ SpD Assault Vest Solid Rock Rhyperior: 183-219 (82.4 - 98.6%) -- guaranteed 2HKO <-- best case scenario with a severe loss of offenses
116+ SpA Rotom-W Hydro Pump vs. 252 HP / 4 SpD Assault Vest Solid Rock Rhyperior: 252-300 (113.5 - 135.1%) -- guaranteed OHKO <-- something more typical for both Rotom and Rhyperior

On a side note you'll tank special hits better than an Eviolite Rhydon:
