6900 yards is an impressive yardage to still shoot 90. You’re too hard on yourself, stylin. Bad knees on a golfer is a tough break though. There shouldn’t be much standing in the way of keeping your short game sharp until the knees are replaced. Between the new knees and a great short game, you’ll have no trouble at all breaking 90 from the tips.
thanks for your kind words. I can’t seem to put 2 nines together. or when I get close to breaking into the 30s on a nine, the wheels fall off.
