Arvin... the 2 hickories are 63, and 64 inches nock to nock with slimmer design. The 2 Osage bows are 63, and 64 nock to nock with a 1/4 inch wider profile through the length of the bows. 18 ounces mass weight with the 2 sinew backed Osage, and the 2 hickory bows 16, and 17 ounces. Tomorrow I am going to test them again to see if I get the same readings. Some thing seems off to me.
if your osage bows are slightly wider than the same in hickory, then its possible the osage ones are slightly overbuilt in the sense they coulld have theoretically been narrower and thicker (on account of the fact that osage is supposed to be able to bend further than hickory, all other things being equall, or said another way, slightly thicker and bend the same distance).
if taking early set while tillering out those bows told you to take more off the belly, then
that piece of osage was not as good as hickory.
if you find your self retillering stronger bows to lesser poundages as you get older, do you reduce widths to reduce weight?
