I had one yew bow shot 50 times or so, it exploded in 5 pieces. I blame it on dryness, but have no numbers to prove it at all. It just looked dry after inspecting the pieces on the ground. I wonder if ring density plays a MAJOR role in whether a yew bow survives extreme dryness? That little bit of extra strength may be enough to pull it through? The two yew bows Ive attempted have broke, both were very low ring count, like 15-16 rpi.
