Thanks for the kind words, I appreciate the feedback fellas.
Buckthorn seems to be really sturdy wood for the most part in spite of knots and flaws. Although there also seems like there can be some staves that look perfect and just won't bend without breaking, usually snapping in tension for me. Also some will hold onto reflex very well and others have taken set easily. This one didn't want to give up any of the reflex in that bottom limb although I imagine a lot of that had to do with keeping the draw weight low.
Here's a pic of the natural reflex in the stave, this picture was taken right after I had roughed it out with a hatchet and rasp some 4 month's ago.
