Well, I know that Frank Thomas is wrong in that regard, then, since Wishon has fairway wood heads that are 0.830 COR today. They even have low profile fairway woods that get to 0.830 (see Tom Wishon Golf Technology ). I know that there is at least one other company reaching the COR limit on their fairway woods today, I think Tour Edge (I'll look for the company I'm thinking of tomorrow), though I suspect that many are pretty darn close today.

That's why it will be very interesting what these irons test at. If they get close, everyone will be titanium in a few years.

Now, how much COR has to do with distance, that is a very fair question. It will be some, but really only a tiny amount, especially when we are talking about something like an 8 iron. Maybe 1/2 to 1 yard? That's just my guess, I don't know for sure. But, has anyone ever turned down extra yards? No one that I've ever known.
