Cool topic to bring up. I have made a bunch of silver maple longbows that end up taking 2 inches or more set, with chrysals even, that out shoot the crap out of my reflexed osage longbows, and I mean bows with around 3 1/2" to 4" natural reflex. I am sure this is mostly because of weight. Silver maple is like styrofoam light, and makes a very fast shooting bow. There is only so much you can do to eliminate outer mass with a heavy wood like osage, there is definitely a limit. I'd have to custom make my own horn nocks anymore for my osage bows, because the tips are like needles.
