boog not to sound like a smart a__ i appreciate your opinion, but it would seem to me that if you use a machine alot more than another than obviously your going to find more with the one you use more, and it would also seem easier because you use it more. kind of like if you lift weights with your left arm 6 days a week and your right arm 1 day a week of course your left arm will be bigger and will lift easier. best way i can explain it.
