I think the performance of bows varies so much it's not as simple as 60 or 70.
With my two bows one would have to be set on 70 to have the power of the other set on 60.
One bow has an IBO rating of 344 and the other is rated at 320 (which is not slow).
PSE X Force 59# 29'' 340 gr. @ 315 F.P.S. = 75 LB of KE
Hoyt Katera XL 59# 29'' Z Cams 385 gr. @ 277 F.P.S. = 65 LB of KE
Pull 60 have the power of 70 if you choose the right bow.
You are Right!!
I am Loving my BowTech 82nd Airborne. 60# 28" Draw producing over 70# KE. A Mouse Fart would rival the noise this bow makes, and it absolutely stacks the arrows. I am getting a 2nd one if that tells you how I feel about this Bow!
