Duke:

Did you change your setup? I mean....you affect spine when you switch head weight.....and I was wondering. I switched from a 125 (fixed)to the 100gr Rage and I didn't have to change anything. I'm shooting a/c/c 3-71's. Just wondering. I don't know much about this kinda stuff. I just know I OVERspine my arrows because my setup allows it.....and I get a little more arrow weight, that way.
