JakaB,
I've played to its former location, and I've played to it's current location, and I've looked at a number of photos or the former green, and in my opinion, it's now a better hole.
The configuration of the old green and old bunker was such that a good distance intervened between the two, perhaps 30-40-50 feet.
If one hits an ideal drive to the flat, center-left of the fairway a relatively short shot existed to the old green. Even if your ball remained on the slope of the fairway, there was no intervening bunker or feature to impede a shot into that green.
Perry Maxwell saw the merits of moving the green back and up onto the knoll behind the old green. It dramatically altered both of the approach shots I described in the above paragraph as well as any attempt at recovery.
The area of the old green was naturally wet, and being in a hollow, the tall surrounding trees prevent ample sunlight from reaching that area, and create shadows that keep it damp.
I've never heard anyone who has played the hole, state that the old 10th was a far better hole, or that the old 10th should be restored. I have however, heard that comment from people who have never seen the hole in person.
The present 10th hole is a terrific golf hole.
