Nice! I've made a sass bow very similar to that one and I think I'm going to try my hand at some sassy ELBs soon.
Here's mine.
http://www.primitivearcher.com/smf/index.php?topic=38158.0I think the biggest reason most people have a bad experience is sass is most often found in sapling form with a high crown, and being a tension weak wood, its not going to turn out well. So try to find a bigger tree and make it wide, or as I've heard, round the belly and ELB it.
I really enjoy seeing other sass bows and I look forward to seeing more in the future.
I really do like it as a wood. Very light weight, easy to work, and some of the most prominent grain contrast I've seen. You should really try staining that with min-wax or something to bring out the grain.
