For those who don't seem to understand a "thumbless" grip is preferred by guys with small/weak wrists whereby you actually allow your wrists and hands to bend backwards perpendicular to the forearm, and the bar rests on your palms, cupped by your thumbs. As opposed to a normal "overthumb" grip used by guys with big/strong wrists in which the wrist and hand remain in line with the forearm.
With my 6 inch wrists, you know why I preferred the thumbless grip. The thumbless grip also allows one to focus on just the pushing, rather than dealing with the stress on the wrists. Wrist wraps can be a big help when benching heavy with a traditional grip. When I put up 465 in a meet last year, I used wraps with a traditional grip.
