Thanks everybody. Ed, I tried all kinds of arrows for the flight shoot. Fir, cedar and bamboo. The bamboo shot as well as any arrow. They weigh about 260 grains. I for sure have room for improvement making flight arrows.
I have one nice piece of Siberian elm to try out. I think that wood is a contender.
DC- Haha! yes, a slow tiller is taking your sweet time getting the bow to full draw. Lots of gradual bending over the span of weeks to slowly train the bow to bend and not shock the wood cells on the belly.
Mark- The handle is stiff but only for about 3.5" in the middle. Wanted to spread the load of the bend as much as possible with a short stiff grip. Good observation by Ryan.
Ryan- 1 3/4" widest tapering to 5/16" below the nock. weight of bow with string 18.5 oz.
