Just wanted to thank Will at Black River bows for the opportunity to shoot the bow. Thoroughly enjoyed shooting the bow. My preference of the two limbs provided was the longbow limbs. No shock or vibration. The string on the longbow was B50. The recurve (FF string) had a little vibration and had some noise where as the longbow didn't. I was told by Will that the bow was made for a 30 inch draw. My draw wasn't long enough to get the optimum performance the bow could provide. But wheather or not my draw was getting all the performance it could, it was flinging my arrows (GT Expedition Hunter, Easten Carbon Raider, Redhead Carbon Fury) faster than my bow. Pleased with the overall craftsmanship, riser handle feel and special designed limbs.
