Foot bows aren't all that innovative, they've been shooting competitive flight bows with feet since way back in the black and white film days.
Guys that build bows to hunt deer in the woods scratch their heads at the nutjobs that tinker away in their garage building something that is going to blow after only 15-25 shots thru it out on the Bonneville Salt Flats. But ultimately it's those nutjobs that really dialed in some serious data on efficiency, low drag, high speed, etc that we use today in tweeking our hunting bows for best cast and accuracy. Two sides of the same coin.
Lemme know when you got that bow done, kid. I got some spare cedar fenceposts I can fletch for ya. Sounds like what you are building is the bowyers version of the Armalite .50 BMG!
