Actually sounds like any very high aspect wing actually. Even the the edge lei liked to be boosted like this in crazy conditions, it drags your sorry ass down to the water whether you like it or no (as your kite should not be in any position loft you IMO), yet on the water it's controllable.
What weight and what board were you on? Choppy or flat conditions?
Thing is I don't know if many retailers will have these as demos ?? Hope so...
Yeah the Speed 1 was a very high AR kite. I had a proto 7m which was so very very thin....
when it came out (production) it was a little less high AR
Here is the designer paragliding under the 17m
