i just made a bow from wide ring,, it seemed a bit sluggish to me, I had over built the bow ,, it had a bit of telling hand shock,
but after reducing the limbs and final tiller, ,a bit of heat treating ,, it shot as good as any bow I have made,, and held a nice unbraced profile,, about one inch of reflex,, I really think its a bout the given tree,, and age of stave as much as anything, yes size of ring is part of that,, but just a small part,,
