re: What age did you older golfers move up to white tees?

We have the following from longest to shortest:

black(champ tees)
blue
white
red (65+)
gold(women)

Typically we play a blue/white combo in our games. Blues for p4 and p5, and whites for p3's. If you are 65 and want to play all whites, you aren't invited

this speeds up rounds as the par 5's arent as reachable, but doesn't require 200 yard shots into p3's
