We had just finished a wonderful day of golf and I shot a personal best 83, I know not great, but for me, at 70, it works. The tees, I think, seem to help the ball leave the tee more easily and I have to admit somewhat straighter. This is the 5th round I have played using these tee's and they seem to work very well. However, I must say the ball placement and stability is a little more difficult. Not sure why but the ball doesn't stay on the tee as easy as standard tees. But the pay off is greate...
