I've got a Blue Moon Exile UL you are welcome to try. I try to fly at Delta Park twice a week.
You should definitely try this one - its a UL, but it flys lower (with a loaded sail) than most full-sized SULs that I've tried. The thing I like most about this one over the Shadow, 4D, Inner-Space, etc is that it pretty much feels like a full size Exile - no "twitchyness" or special handling required, just fly it like the standard but in less wind with more drive.
If you like the loaded-sail feeling of the Shadow then you will probably like this kite as well. It reminds me of the Shadow in some good ways (good low wind drive, loaded sail, older school but does new stuff as well), but bigger, better made, and more stable. Ken's kites have a "smoothness" in flight that is hard to describe.
