My last (and best so far) bow had at least 180 degrees of twist in the lower limb. I figured, meh. Wouldn't be my first failed bow. So I roughed it out green, left it to dry. That's when I found out that (at least with serviceberry) the twist actually WORSENS while drying. Oh well, I cranked on the tip while applying heat, and improved the situation (at least at the tip). Tillered it out as much as I dared (probably 25" or so) and backed with rawhide. I'm pretty sure the rawhide is key to this working. Plus; I'm pretty sure the high crown helps lots, too, because at the bow's edges the bending stesses are close to parallel the twisted fibres rather than in a shearing plane. I'm expressing the concept badly, but I hope you understand what I mean. Anyways, long story short, the bow is 59 1/4" long, sweetly draws 28", I've put hundreds of arrows past her gopher-furred pass, and even kilt a b'ar with er.
