I have an osage stave(piggy back),that,if built the normal way ,(the outer most good growth ring used as the back of the bow).will be a very difficult build due to wind checks and knots,while, if flipped over,and chasing a ring from the inside/out,should yield a clean stave. Some time ago,I read at least one account of building a bow like this. My question is: How is the bow holding up?Has it (or them) been tested by time? I can pull off the harder build,but I'm curious,and would rather have a clean back. Sure would appreciate feedback if any of you have done it,or know someone that has. Thanks, God bless
