I’ve played some with speed, and when I saw there was little room for significant gains if the original design is good I went for other properties.
I appreciate your test, and had to laugh when the conclusion you reached was similar to mine. I hear the bow tip mass opinions pretty frequently, and reasonable limb tip mass weight is quite insignificant. I’m sure it could get carried away but it would be tough to tell which bow had what tips shooting blind folded even.
Yet building more bows is always promising!
