Mark, that bow is a real good example of how much power typical bows loose to hysterisis, very rare for a self bow to approach 180 fps with 10 grains, yet that bow performed at the top of the scale for even laminated wood bows. It also demonstrated that a lot of us may be underbuilding our bows and not realize it. My 35# bows will very often outperform my 50# bows when shot on an equal grains per pound basis.
