Keenan,
How are you doing my friend? I hope your recovery is going well.
I found service berry to be a surprisingly strong bow wood. A vine maple bow with similar dimensions would pull about 45 lbs. So the wood is very dense - almost like osage. I don't have a chrono so I don't know how fast it shoots, but I'm very confident it would take down just about any N. American big game if the arrow is put in the right place. The wood is easier to scrape than vine maple because it does not chatter like VM will. I kept the belly flat so I'm not sure how resistant to compression it is. The next one I make I'll radius the belly somewhat and see how it holds up.
