Im going to build the bow & find out the self bow in the the pic was the fastest bow I had ever made with fresh numbers well into the 180s 10 gpp & was shooting 12 gpp arrows well ,but the bow was to heavy draw for the design and eventualy broke down so here are my thoughts I could go hickory/sinew or a very narrow osage 65 ntn slight recurve 18-19 in. working limb the hickory would be the lighter mass but better compression strength on the osage, I have pristien staves in ethere well cured ?
