ValueGolf Those heads were designed specifically for Bryson, and I doubt he has any need for high-COR faces with his clubhead speed. And I can't image that those will bear any resemblance to Cobra's SL set that they release for sale to the public. They aren't going to start selling SL clubs as a forged CB/MB combo set which would only work for maybe 2% of the best golfers in the world, especially since those type of golfers are going to be the ones most resistant to the "untraditional" SL idea. I guarantee that the design they release for sale is going to be more of a super-GI design.
