I just finished a 17 zone 86 head install. Took 2-4 guys (depending on the day) 5 days to do. I think we did pretty good. Problem is, its in a real windy area (Right on the Straits of Juan De Fuca), and its been blowing so hard that I haven't had a chance to adjust it. Do you guys adjust for the wind so that on a calm day it doesn't cover enough, or do you adjust for the calm days and expect mass overspray on the windy ones?
