8.25 or 8.75 rear

Sorry for the late response guys. The last week and a half has been a killer. Thanks to everyone's input I think I've narrowed it down to the 8 1/4 or the 8.8. The 8 3/4 sounds great, but if I can find the 8 1/4 or 8.8 for cheaper, I think one of those will be stout enough for my needs. Thanks!
