Had this 64" deflexed stave laying around the shop for a few years now.  I decided to cut out a couple of bow blanks and thought I'd give this one a shot.  One limb was about 3" deflexed and was no problem, the other was closer to 6" with a little dogleg to boot.  Clean little piece otherwise with decent rings.  Kept waiting for that "tink" sound of a splinter popping but never heard it, and with patience and plenty of heatgun I managed to clamp it to the form.  To my further surprise it held most of the shape when I released it the next morning.  Needs some touchup work but its got a nice bit of reflex already.
