I used to use straps on everything, especially weighted chins. My grip is much better now and is no longer the limiting factor (I will be hitting a 500 dead any day now, literally). My grip has developed quite a bit with the use of thick bars (rolling thunder etc.) and grippers. I agree with Hulkamania, don't use straps, period. I see way to many people relying on them. Thanks to this board, I am no longer one of them.
