Brad, sorry that I haven't answered you already. The riser ended up at 15" and the limbs were designed to make it a 66" bow with a 17" riser.
It is 64" and on my cheapo bow scale it reads 55#@30" which was literally the exact weight that I was praying for!
I deviated slightly from the Bingham's plans but even so, I can't get over how well this bow shoots. I know, I know, even parents of ugly kids think that their baby should win beauty contests, so maybe I'm guilty of that...
I used two parallel maple lams in each limb and altered the limb pocket angle slightly. It is more quiet than many bows that I've previously owned and shoots pretty darn quick although I have nothing to relate the arrow speed to. If I ever get around a chrono I will send some downrange to see what it is capable of doing at 28" -- I draw 30".
