I have an '08.5 Z28 shooting 62# and reaching 282 fps consistently with a 338 grain arrow, 27.5" DL. I have a set of limbs that will take it up to 70#. My question is this; If I put the 70# limbs on and shoot it at 65# to 67# what speed will I gain?????? Just trying to decide if it's worth it or just sell the limbs?

I put new limbs on my 60# GT500 to bring it up to 65# and I really love that weight. So, I'm considering making them both the exact same weight.

What do you all think??
