Dave,
I read your prior posts and was amazed by the amount of reflex that you were able to retain after shooting in those BBH. At 68, high 30 to low 40# is plenty of weight and I no longer fling broadheads so mine are basically 3D oriented. Yes, Meadowlark is the culprit that gave me the stones to reduce the bamboo from the back. Time will tell if it was a bad move, but it wouldn't be the first one to fail. Any heat treating I've done was the good 'ol heat gun and it certainly made a difference with correcting some bows that needed it and increased poundage as well.
I'd bought a bundle of 25 bamboo slats - 6'x2" years ago, and they're gone. Last one is on "Nodeless" - guess that is what I'll call that bow!
