I think that settles it. Looking at Mike's new bow (even though it's HHB) makes me go with the hickory option. I've been waiting for this black locust stave that I roughed out to dry, but I don't want to rush it and I'm tired of waiting. I've got tons of hickory ready to go, it's been drying in the barn rafters for a couple of years now and should be good.
Now that I think I've made up my mind on a plan A, I might just start tonight (I'm heading home early anyhow.) Plus, this is my first weekend in months that hasn't been filled up two weeks ahead of time. I'll see if I can't get some shavings pulled off of that bow and post some progress pics by Monday.
