Thanks everyone, I'll probably just play it safe and go for one bow out of the bigger one, plus I'll see if I can de-crown some of the smaller ones.
mullet- I really appreciate it, I'll see if I can get in touch with him sometime soon.
Weylin- I'm probably mistaken, but why the tension/upper side of the log versus the lower/bottom? I heard something about gravity naturally pulling the wood fibers closer together on the bottom/underside of the log, making for better fibers and grain pattern, but that was quite a while ago.
