IMO, I think golf courses have different sets of tees for specific reasons. Just like handicaps, different sets of tees allow people of all abilities to compete with each other. From my experience there is no reason for people to play tees that do not meet there ability level. Im not just talking about mid handicappers playing from the tips, I am also talking about Low handicappers playing up. While it is fun once in a while to play outside your comfort zone, playing tees that are not where you should be playing from often make the game of golf less fun and more frustrating. I play with a friend of my brothers every once in while down here and he is probably a 15 handicap and insists on playing from the tips (usually 7000+ yards). Its sad because he gets really frustrated with the round and his play. The only reason for his frustration is his tee selection. I have also found it uncomfortable for me when I move up a tee sometimes. People say it just gets easier but thats not true, it takes Driver out of my hands on many holes and I am hitting clubs into greens I am not used to hitting, also many times more trouble( hazards..etc) comes into play when you move up a tee. Like I said I feel that golf is unique in the aspect that people of all abilities can compete with each other but a big part of that is playing from the tees recomended for your handicap.
