yeah, I think Wilson stated that above a certain level, there were definitely diminishing returns with this frame. translation, they have such good technique that they won't benefit and probably would wind up changing frames every 3 games due to breakage.
but for us mortals who love an open string pattern, it's definitely a boon!
