The Critical Draw skill is best used with Greatswords whose main form of attack is the unsheath, and Hammer superpounds (Must DRAW into superpound), the superpound will be critical for both the upswinging motion and the actual pound itself.
An effective combination for this armor, is to use Rathalos waist and legs armor. Then use the two slots in the leggings for an assault jewel, and the remaining slot for an element jewel. This rids you of elemental attack down, and gives attack up (s).
Another effective combination for this armor is to use Baggi waist and legs. With another two slots between the weapon and charm you can gem in fast charge, a magnificent skill for both hammers and greatswords alike.
