Michael, that design is looking fantastic. I may need to go even more narrow with my tips just to edge you out.
I was thinking a lot about that short pyramid red oak in TBB4. Even when only drawn to 23" it still had excellent speed. Keeping the same limb design but adding a long stiff handle would increase fps slightly if kept optimal but the tips would bend just as far as the short one so draw would still be limited to 23". My thought is that if the design could be extended to have a 28" draw, for increased energy storage, it may be one of the fastest designs out there. Keeping the same ratio of bow length to draw length, a longer bow of the same design would be 73" long for a 28" draw allowing a 7" stiff handle for an 80" bow with the same limbs. I may need to build this sucker.
