Played a singles match for my USTA team the other day - we were playing away at an upscale private club. Prior to our arriving there, they had put up singles sticks on the two courts designated for the singles lines. I thought that was a nice touch, since honestly I can't remember when last I saw singles sticks in use for league play.
So... how common is it to find them used in leagues? Do you have them in place for your home matches?
