RE: Speed vs quietness, what's your priority?
My Outback that I sold on Ebay last week was a 60# draw...but got 271fps...absolutely silent. Overall though, I'm truely a silent shooter over speed.
Like posted above, arrow speeds aren't even half of the speed of sound...so what's the difference ofa 310fps arrow and 270fps in reality? Basically nothing. It's all perception and marketing ploy.
