As an 18 hdcpr, you will do your team more good than bad, as long as you play your normal game. We have a 16 hdcpr who plays with us, and not one tournament had been entered by us where the higher hdcp player did not help us finish high, or win. Any good shots, natural pars, or birdies you score are nothing but pure gravy to your teams' score. Go have fun, as you are there for a reason. GJS
