RE: FAST??
Really not all that much difference, Gary. I put an STS on it - bowjax on both limbs - and bowjax on the cables - and she's pretty quiet. All you can hear is the string slapping the STS bumper.
I agree though - it's a personal preference. And I can see both sides of the fence. But honestly, I think the perceived "need" for insane KE is overstated by most on this board.
I'd take a better trajectory 10 times out of 10 - as long as I'm hunting whities.
