I play a country club social league as well.
I have learned over the last year to in no way take it serious or "competitive".
I use it as a time to try tactics and play styles I would not normally in a match. It gives me valuable "match like" scenarios to try and improve my game.
I get along with everyone great and if I loose some matches to an older/inferior opponent I actually feel good if they arent a @ss about it and I see how happy they are.
Using Wilson 6.1 95s Kirsh Pro Line X 17 @55lbs. Why did I ever leave Wilson?? Gotta stop being cheap and trying to get racquets for $50!!!
