The drag curl sounds pretty hot....definately gonna try that one (but with dumbbells). As far as hammers, alternating, or supination curls, I always try to use my bicep only...as in flex it hard during both eccentric and concentric motions. Force it to do all of the work.
Oh yeah, and I train bi's from a primary workout standpoint with dumbbells only. No cheating and it keeps me even.
