Wow, good ideas, although unfortunately I'll be gone for the weekend and can't put any of them into effect for a bit. I'll post some updated pics when I get back though.
Randman - D-eflex R-eflex? It seems like deflex would take poundage off. As for heat treating, I actually did do a bit on this one (did it fully on my first OS bow and it definitely helps) but only on the area with the slight hinge. It did take a bit of the hinge out, and I'm afraid that if treat the rest of it that will be undone, although I guess I could scrape the face and tip areas to compensate.
Zion - Your bows are scary strong, I'm not clear I could even draw a 65 pounder!
