Hello Dean,
I have been flying sportkites since 1985, and both Bordelan's and Makka's (Warren) MEFM's since my first one in 1992. I have about 9 different variants of the MEFM design from Featherlight, and Microlite, Standards through to custom 2, 3, and 4 vents.
If you are looking for something to fly in zero wind outdoors, have a look at Makka's Microlite. It is something else indeed, as nothing else comes close to it. Rays featherlight, was innovative for the time, but Makka's Microlite is a dream on 15lb, 20lb or 50lb. The longer the flying line the better too outdoors. These days I use more modern designed S, SUL, and UL sportkites for indoor, tricking, pairs, team, and quad. Then there are times, when I wish to fly individual precision and ballet routines for demo's, and wind depending, I still revert back to MEFM .
Regarding Scott A, I still have many videos from WC's at Seaside, Berkley, and Japan. Also some from my time in Hawaii, when flying individual, pairs, and team at K park, and with Rob and Alan from Team HPK.
Now those were great days, and excellent times in sportkiting. We were all dog staking Rev, as well as Rev and Dual flying back then. Some of us from time to time still do now, as it's no big deal. Though this is a personal choice more so these days, as "old school is still good school"..

Merlion
