I'm on my fifth bow (3 flat pyramids and a Mollegebat before this) and have decided to try reflex-deflex....glued up a hickory backed Ipe, 72" long, 1 7/8" at the handle, tapered to 1/2" at the tips. 2" of reflex. I've got it thinned to 1/2" and am ready to start tillering. Now.....do the reflexed tips need to bend? Or act as levers?
