What's better for curls — the EZ-curl bar or the barbell?

What is better for cutting - a steak knife or scissors?

Better yet - what's best to paint with. Yellow or red paint?

My point is that, to train your biceps, you must bend your arm. How you bend it can be done in a variety of ways from straight barbell or EZ-curl bar to anything in between. If the straight is uncomfortable, use the EZ. You're not missing a thing.
