What are your comments on the Ozone Frenzy?
I currently have a 4 line sting 2.4 and an ATB, but need to upgrade to something a little larger. I was going for the Ozone Frenzy but need some comment on it before I buy.

Thats a big jump from the sting to a frenzy. Im sure you can schedule a demo there in the UK or find someone who has one. Never flown one but always seems to get rave reviews. Regardless, factor in your weight, avg winds, budget. Winds picking up for the winter so factor that in. Other options are the Air Evolution, and the HQ Montana 3. The Trowbridge guys (TAL) setup demos often with the Evos. The Montana 3 should be out within a month. With improvements over the Montana 2 and the price staying about the same, it deserves a hard look/demo. Good hunting, shouldnt be a problem over there.

Yeah, but as tridude says, that is a big jump - the power per sq.m is massively different!!!
