I've been using a 17m Ozone Zephyr for the last year or so for light wind cruising. It has been a very good light wind kite for me. I recently picked up a 19m Core Riot. I've only got a couple of hours on it, but here is a bit of info for others who enjoy light wind Cruising.
Span (flat): Riot - 30' Zephyr - 28'4"
Width or chord at mid kite (flat): Riot - 7'6" Zephyr - 7'
Weight: Riot - 11lb. Zephyr - 10lb.
Note: all measurements are approximate
I rigged and then launched the Riot19 in the water. Wind was 7 to 9 kt as measured by a Sailflow station about 500 yards away. The kite easily rolled up onto a tip and launched. After launch, it was stable overhead. I kited on a Sector 60 and and a Flydoor XL and enjoyed the session. The Riot19 was smooth and very controllable. Compared to the Zephyr, it seemed to launch off the water a bit easier, provide a bit more power, and it did seem to turn a bit quicker. This is strictly a subjective observation as I did not have my Zephyr rigged for side by side comparison.
After a couple of hours, the wind built to 17 kt. I switched to a CrazyFly LW board which was the smallest board I had with me. The kite was controllable and I was still having fun, but then I'd never rig the Riot19 for anything over 10-12kt.
I'm 170 lbs and have been kiting a little over a year. I'm not a finesse guy so I need a big kite and a big board to get going in light air. Not a dealer, rep, or promoter - just a guy who likes to kite in anything from 8 to 30.
