I think a concept w/ the "speed bow" that is oft overlooked is efficiency and KE. Folks NEEDED to shoot high poundage to get speed and KE out of their set ups. This is simply not the case anymore. Jeff's rig is a good example. What was your arrow weight Jeff? 327 right? Not heavy...BUT, he's shooting 330 on 62 #'s. He could shoot a much heavier arrow and linger @ or over the 300 mark and carry unbelievable energy.

A major plus to a speed bow is the ability to shoot a heavy arrow fast. Case in point, I'm shooting a 440 grain arrow @ 296. Talk about KE. Not that long ago that just wouldn't have been possible unless you were shooting an 80# bow.
