Bows, for the most part, are personal preference. Having said that, I've seen a lot of osage bows, particularly at OJAM, that are just over built. Long equals heavy. Wide equals heavy. Get the weight off, way off. A light weight osage bow is a rocket launcer. 70", in my opinion, is insane. Most of mine are 60-62". The same goes with the width. Take off the excess weight. I have never understood why in thw world people use such over built osage bows. There is just no way they can compare to a lighter weight bow, and with osage, you can and should use design that allows for this.
