first of all i have both the Unbelievable and Cost of Redemption and i watch them on a regular basis but Cutler's approach to the sport impresses me more, Ronnie is a mutant for sure but i think Jay trains just as hard when you consider the volume, rest between sets and with the exception of deadlifts and squats Jay is really just about as strong as Ronnie on the other stuff, i'm just tremendously impressed with Jay.
