I get your point pat and agree. Point being, its a bow trade not a bow order. Do your best to make one the other guy can use, but perfectly is not a requirement.
Whip tillering... wanna fix it? Pike it. Shorten the limbs, that makes the tips stiffer, then weaken the inner limbs to take stress of the outer, and voila, you have a nice bow tiller. And you wont loose any weight.
