I can't say I've moved up 1,000 yards, but the golds at my home course are pretty close to 800 yards shorter than the whites. I have played them a number of times, and enjoy the hell out of it.
There are several reasons i don't play them more. First is that their current location has never been rated, being 400 yards shorter than the card. In addition, I found that I play WAY better from them, so even if I adjusted for the shorter yardage, I was dropping my handicap too low to be competitive in my men's league.
Anyway, I can just handle the tees @ 6,332 but find a 5450 tees a lot of fun as well. I assure you, however, that there's not much enjoyment for me back at 7,400.
This week I was at Karsten Creek for the NCAA Div. 1 Men's Championship, and they have tees at 5,000, 6,000, 6,600 and 7,400. Only a gun would get me on the back tees.
