I used to be in the wrist-wraps-are-for-pussies camp. Two things changed that.
First- I put a pair on and was amazed at how much easier it was to control the bar and keep in the groove. When I would take a heavier weight without wraps- really anything over 300- my wrists would bend back. I am pretty flexible and this was not uncomfortable usually, but it tended to make the bar drift back from where it should be- over my elbows. With wraps on, I have an easier time driving with my elbows.
Some might say that wraps make your wrists weak. Maybe this is true, but if you can keep in a tighter groove benching and handle more weight, everything else (tris, lats, etc.) will get stronger faster.
The second thing is that changed my mind was training with 600 and 700 lb benchers and noticing that they took very good care of their wrists- using tape and/or wraps on anything heavy- even warm ups.
Give them a try. They are the cheapest piece of powerlifting apparel out there and dollar for dollar, one of the most effective. I use a short pair of Titan Titanium wraps (16 inches I think) and a longer pair of Metal triple line wraps (30 maybe). Both are good.
