Three coats on, and I really like the way the EM sprays. If I sprayed it every day, I'd probably use the 310 for coverage in one pass. Not doing it very often, I think the 308 is more forgiving. We had a 7mph wind on the lake, and some more than that at the top of the hill where I was spraying, so I had to stay closer than 12", or the wind would blow too much of the fan out. I didn't see any need to even try the 306 Tritech tip.
