do whatever places the least or no strain on your wrist.
after say 2 sets on straight curl, i feel a slight strain on my wrist, when i feel this, i finish my bicep routine with 1 or 2 sets of ez bar curl. i try not to do more than 3 sets of 10-12, just keep it intense and make sure your elbows are tight next to your side, when you reach the top, theres no need to lift the bar up so you can rest it in a position under your neck. at the top, the bar should end up say about 5-7 inches from the top of your chest, keep there for a sec, then return to start position. for super strict form, do this against a wall or a bench, but in the bench, put some weights behind it because youll find yourself moving it back.
ive seen too many guys do heavy weights on curls but with utter crap form. then when i do mine, they see my form, next time i come into the gym, i see that theyve decreased the weight and started to do curls against the wall or leaning against one side of the squat rack
