I wouldn't give up yet....you will need to break several to learn.

I was on number 5 before one shot more than a few times before breaking. It is now a few years old and has even survived the string breaking and a dry fire....I have not had great luck with subsequent attempts(3) either. But as baker says..it is all in the design rather than the wood...he made durable bows out of fir and willow.
The bow i talk about it a maple self bow of 55 pounds at 29 draw.
