close grip is very good, insane stretch at the top. It is all a matter of preference. However, I defy ANYONE to tell me that you do NOT get a better contraction with a reverse grip. Do this experiment. Do both reverse grip and overhand grip. Try pulling your elbows back on both as far as possible. You will find that it is physically impossible to pull the elbows back further w/ overhand than under. Its simple physiology.
Crak, the close grip version is one of my favorites. I will on occasion add these to my routine.
