Last year i built an osage bow that was 72" long 140#@32" but was a crappy shooter even though it took no set so I scraped it. Building a 71" right now for a 28" draw @ about 110# maybe 120#. Have no clue yet how this will come out, If the wood shows signs of stress as I work it I will back off on the draw weight. This bow will be an elb flight bow. The 140# felt like rubber, easy to brace and low early draw weight. Steve
