I finally got some time to rework this design and considered using all osage in the core/belly lam as suggested but weighed the two cores to see how much weight difference between the the two and the bamboo comes in at a solid 1 1/2 oz lighter Aples to Aples it's a huge mass difference , decided I'm shorting the design to 64 in. & going with reverse wedges & sinew for the back I'm only going to sinew up to the start of the maple wedges that way I can control tiller & mass better !
