Working on my trade bow, it is 65" t/t Hackberry. Have it tillered to 28" and have put about 30 - 40 arrows through it. Has some hand shock, not bad though. I'm ready to start final shaping of handle and tips, how narrow can I go with the tips, they are 3/4" on top limb, and 7/8" on bottom limb. I plan to add tip underlays, there were a few cracks that developed when bending the tips, they are only into the first ring on the belly side, the underlays will be insurance. Plan to use cocobolo and osage for underlays......Dan
