I'd be interested in knowing how that bow performs. Seems like a bowyer could make a bow that would withstand a lot of dry fires, if he was willing to sacrifice a lot of performance.
A couple of years ago I blew out the top tip on my Black Widow recurve in an accidental dry-fire, from full draw (31"), on a 62@31" set of limbs. Dragged the tip of the bow about 2 inches through the fiberglass into the limb. Bow never unstrung, and remained all in one piece. Wasn't a good day for me though.
