I've been out of the game for a few years now, and would like to start shooting again, but my 60# osage selfbow is a bit much for me.  I was considering retillering it closer to 50#, and was wondering if anyone could give me some advice on this.  My biggest question is whether or not it is a good idea to retiller a bow to a lighter draw weight, or if attempting to do so will potentially damage the bow.  Any advice would be helpful.
