SpikeMaster I haven't made a lot of bows but for me the white woods (hickory, elm, pecan.....anything you don't have to chase a ring on) is easier to start out with. I'm not great at chasing a ring and it takes me long time to do it right. However once you learn to chase a ring, woods like osage and BL are really nice. I haven't built an osage yet but I've chased rings on several staves. You can harvest BL all around where you live. I grew up in Clarksburg so I know it's pretty abundant around there.
I've built several hickory bows and I do take care to control moisture when building them. I built a hot box to really season them out and to keep them dry when I'm working on them. I usually put 6 to 8 coats of finish on them. I have used Spar Urethane and the Massey finish and like both. I also put several coats of a good past wax on the bows several times a year, expecially right before hunting season. I haven't noticed any real lose of weight when shooting in the humid summers. The humidity is usually a lot lower in hunting season so I don't worry much about it then. But you can alway keep them in the drying box to help keep the moisture down.
