This lever bow, wide and long, broke around 70# and 24" draw while I was exercising it. Actually, I think I know why, I didn't trust it all along. But it was almost there, a bit stiff in the inner limbs still. And I liked it, too.
It was probably too dry. I had the option to keep it in the workshop where it's frozen, or inside in the heated house. Chose inside, might have been a mistake. Second, the wood (sugar maple) was questionable. A bit of rot and bugbite here and there. And this knot wasn't making it better, either.
It really made a loud bang, but I myself got away
