Sorry for delay in replying.
I'd say the Infinity is a good kite and I prefer flying it to my Hypnotist. It sits much better in a Fade, is lighter which makes it easier to trick, has a much more rigid frame with yoyo stoppers and better wing tip nocks which are easier to free lines from and it's pretty robust. It's not perfect. Mine has a bit of a line catching nose where the stitching finish is rough and the stand-off fittings and sail panel edges in that area are also a bit line catchy. The Superfly UL finish on the other hand is perfect. The Hypnotist, perhaps because it is heavier, oversteers less and I think does more elegant flic-flaks. I paid £168 for my Infinity which made it much better value for money than the Hynotist which I think is over priced for it's mediocre quality.
I might have bought your Hypnotist from Kiteworld. I ordered it on June 7th just after Kiteworld had ONE back in stock. It is noisy but I find it flies as expected.
How do you find flying your Deep Space std and UL?
