Sounds slow to me, compared to many other r/d longbows I've graphed recently, including Slewboy, Black Widow, Thunderhorn, and Lightning, all of which consistently graph average 180 with 525, which by the way is 125 too light, according to Dr. Ashby's research, for really big game. I have a Shrew on order and sure had hoped for at least the average these days. Not a speed-freak at all, but just really surprised. But then, that's still 10-20fps faster than any of the several dozen bows I've built myself so far. These days I graph all bows at 650, which is Ashby's min (with all else being correct as well) for sure bone-busting on elk/moose sized game,w hich is all I hunt. Could some of you guys go back and graph your Shrews at this weight? Much appreciated, Dave
