If the routing of the holes close to the clubhouse were not so cramped, Prestwick would be a great choice. As I've said here before, that is a hell of a hard golf course, and I can only imagine the drama that would ensue on the final few holes. Imagine Phil Mickelson trying some different shots around those greens. I think it would be a cool venue, but it's totally unrealistic.
Why not move the Match Play each year? I like the Dove Mountain course, but it would be good to the tournament at different venues worldwide. Since most of the top players now are Europeans, the tournament would have no trouble attracting top talent if it were in Australia, South Africa, or Britain.
