swimbill, missouritrading.com has good bamboo also (but no ipe). I'm just finishing my first boo-backed ipe and hope to post it soon. Mine is a skinny pyramid, 63" overall, 61.5" nock to nock, about 1.1" wide at fades. 50# at 28". Glued in 5" reflex and it holds about 3/4" after tiller. If you've never used bamboo before, there's a lot to learn, I ruined 3 pieces before this one came out OK. I'm also glad I got a bench type belt sander, you have to first cut the boo to the bow shape, then sand it to a knife edge all the way around or it'll be way too thick.
