My grip usually around 6-8 inches which my ring finger willbe on the line. Yeah, the motion will looks weird if going for closer grip.  (got to ask king how he did his close grip bench hehe)

I just read it from the magazine, but i think if training for the inner and outter part of the pac the best still dumbell press.

Remark : seems like recently i have a good sleep and result in some improvement in my bench... 77.5lbs each side ... i m looking forward on 80lbs ech side.
