Thanks for this thread, lots of useful info. I am also trying to decide which UL/SUL to get. I guess where I differ from the OP is that in addition to learning tricks, I am also interested in competition. And I don't yet have a UL.
Just throwing this one in there.
Kite Related Design's FURY SUL
0-12mph. 250cm wingspan.
240gram kite: framed in 2P/3PT/2PX
230gram kite: framed in Aerostuff Zen/P2X
Team kite of the Scratch Bunnies and the child of Carl Robertshaw. The UL has a range of 3-12mph. This is one of my most desirable kites, even above Revs! Just something about it. Pricey though. But custom colours and an award winning pedigree. Not everyone's cup of tea but I hope to be good enough to "earn" one.
Edit: Literally in the last 10 minutes I found out that KRD is no longer! Pretty bummed at that. Apparently Carl was to be still producing the Fury but not very sure.
Oh no, that's a bummer. My local team, AirZone, also flies Furys. I've also noticed that almost half the teams at the 2012 World Sport Kite Championships flew Furys. Big kites. I too hope someday I get to fly one.
