I am looking for feedback on Ozone C4 15m. I am a heavy rider (220 pounds) and looking to complete my quiver of 2011 C4s - 11/9/7. I have flown 13m and loved it but I think it would have to much overlap with my 11m. Do you loose much turning speed and agility when going to 15m? Do you gain much low end?

Haven't tested my 15 vs a a 13, but it gives me enough low-end vs my 12m to justify owning one. That being said, don't expect miracles from it, at 200lbs I'm still on the 15m and a 133 tt, when regular small-ass'ed Joes are on 10-12m Cabs. It has some low-end torque, but it is not by any means a light-wind kite. I have a 70kg friend who rides a 12m rebel, and by the time he can't go upwind anymore, i'm long gone packing and smoking bamboo... though with 4m extensions I can usually pretend like i'm keeping up... On the other hand, it's the most fun 15m I ever flew, and it loops like a charm. Also, it's the best kite i ever had a chance to do a downwinder with.

Thanks. That's a great feedback.
