Well you're 3/5 of the way thru the 5 year trial period as set up in the original premise. Glad to hear it's still shooting.
I thought it took a little too much set originally but wasn't about to say anything negative about such a fine bow. With the 2 1/2 inches on induced reflex from the caul, you should have come out with 1/2" or more of positive reflex when rested after tillering and shooting.
With regards to the overlays popping off, that's why I never recommend anything be glued to a wooden hunting bow that could cause the bow not to function if lost. A glue line is just a possible failure point. Sure we glue on floppy rests, leather handle wraps and snakeskins,even sinew, but none of those will keep a bow from functioning if lost while on a hunting trip.
I still believe that is the finest rigid handle bow design for an osage hunting bow.
