Thanks everyone for the good words...This was my first bow using Bamboo core wood and after some side by side shooting of my maple core wood bows off the same form I would have to say there seems to be a noticable improvement in at least the feel of the bow. I will borrow a chrono from a friend next week and see if I am getting additional speed. Even if the speed is equal I think I will make a few more bows with the bamboo core just for the feel alone. Maybe its all in my head but that's fine if it helps me hit the mark...
