I just got a Skykiller from Antonis and I freekin love it. It has the same deep turtle as the Superfly but not quite so. I find with the fly if you get it locked in you have very few exit options. (Could be a user problem)
The Skykiller has become my new favorite, I've only had it a week though. Been flying with it three times and my joy with it is only growing. For me it behaves a little like the cosmic TC and a little like the Superfly but it holds a fade better than either of those and seems to fall into one effortlessly. It is incredibly well balanced and came with three tail weights for different wind conditions. I've had it up in 4 mph winds and in gusts to 20+. I am very, very impressed with it and recommend it highly. I find myself scheming for time to spend with it.
