I'm catching up on here after the holidays and just saw this one. I'm going to play this game like I have to go outside and make a bow for survival. I'm working a lot with Casuarina (Australian Pine). This far south in Florida wood doesn't have growth rings. Casuarina is plenty available being invasive and I'm finding very good with tension and compression with a specific gravity around 1.0. Plus, if taken after some cold weather the bark comes off in one solid sheath. I'm currently seperating sinew to try a short, perhaps 50" sinew backed D. It seasons in a matter of months for 5-6" trees and a 45# 64" sapling bow can be cut and made within a week or two, taking minimal set without being heat treated or smoked. I would love to see what others on PA would come up with if they had it down the street. I'm seasoning some other things that I've got high hopes for...Sea Grape and Swamp Oak. All that being said...Osage.
