RE: Bad Shot, Read all about it.
I think you made the right decision as well. Hopefully you will find him this morning.
As for the KE question on Spitfires...their modest cutting diameter would require somewhere in the neighborhood of at least 55 ft. lbs to get them to work most efficiently. If you could list your draw length and the specific Hoyt bow that you are using then maybe I could take a guess at your speed and subsequently your KE level.
