Believe it or not, I was able to un-twist a 35# Shakespeare Sierra that was at least as bad as that. Clamped it in an "over-corrected" position for a entire day which got most of it out, then stringing, tweaking, shooting got the rest. Been probably 10 years now, both my kids learned to shoot on it, plus many others. Good luck, and go slow, be patient, and be careful with heat and water.
