Hello Ryan,
At Pumpkin Ridge, we have always played the blue tees the first two days, about 6500 yards, during which the seniors championship is held concurrently. Then on Sunday we play the blacks, about 7000 yards. This year, after some discussion, a blue/black combination of about 6700 yards was used the first two days.
I think the younger guys should have an advantage, and believe courses should be set up at 6800-7100 yards for a good club champion. On the other hand, places like Crystal Downs and Pasatiempo, each around 6500 yards, should just be played from the tips, and I would guess an older player has a better chance of winning there.
