I used a board I first rejected because the grain ran out towards the ends, but there was enough straight grain to cut out the bow on the diagonal.
On my first bow I added a walnut riser and tip overlays, moose hide handle wrap, and generally took more time to finish it nicely. It broke anyway (I'm pretty sure because I didn't round out the edges of the back sufficiently). This one I kept simple, took the lessons learned from the first one, and I think it turned pretty well. I've got a few hundred arrows through it now, with no sign of any problems.
Now a question - what's the useful life on this thing? Like everybody else, I used red oak because of it's availability, not because it's the greatest bow wood. Is there a trend towards R.O. bows dying young, or will I be handing it down to my grandchildren if I treat it right?
