Just curious. I've seen many bows over my life, and owned more than a few, but never run across one with an oak riser. Limbs, of course, have to work, and if you tell me oak wouldn't make good limbs, I’d have to believe you, since I don't know any better. But all a riser has to to is to be sturdy and not break. Oak is known to be sturdy, and is relatively dense and heavy, all pluses in my book, although I realize some people prefer more lightweight woods. People like their risers to be beautiful, but I’ve seen many beautiful things made out of oak. Plus, it's one of the most readily available hardwoods there are. So why not?
