I will explain my 4" width preference. Two weeks ago I grabbed a couple 3" wide snakey sisters from my stash. I peeled the bark and sapwood, went down 2 rings to get to the one I was after. The billets are 1 1/2" wide now and I havent squared up my edges at all, that concerns me. Thats why I suggested wider, you never know how far down you have to chase rings which sequentially narrows the billet. Just a thought.
