Hhmm...OK, I'll buy your argument on that level, but I still think if any game improvement was really good it will show up on tour some where, sooner or later...hybreds are showing up, perimeter weighting is catching on, big head driver, etc..my point being the tour weeds out junk, and I think they do use the latest tech, some of them big names like Tiger, and Phil are getting stuff way before we do..lol...but I don't think they play them in a tournament until they know if it helps.
