elm reflex-deflex, question

[Qwill]

I am in the middle of a Siberian Elm R/D bow, and I need to decide wether or not to back this bow. It's 64 inches long, with a mild deflex and a pretty strong reflex. While steam bending the wood, I compressed a small portion on the outer 12 inches of the lower limb. I worry that will be a weak spot. I could back the bow with hemp string I have, or chase a few rings on the back, or flatten and back with some hickory strips I have. worst comes to worst I could always just lay down some fiberglass... Anyone have any ideas? I'm shooting for about 55-60 lbs. chasing rings might be the easiest. But will that be strong enough? I will heat treat the back of the bow.

 I don't know about Elm, but I've seen that done to osage and I did it recently to a HHB bow. I havn't had any problems with the HHB or the osage. Did you do this with a clamp or did you just bend it too far? Also is it the belly or back?

the compression spot is on the back, roughly 12 inches from the lower tip.
