Hi Fred,
Just thought I would mention that I own both a STD and a vented Challenger. IMHO, they are both very nice kites and the build quality seems to excellent. I am sure that whatever Andy shared with you about the kite is spot on!!
The TICA 202 is also a very nice kite, but as Andy pointed out, a bit bigger and that may cause issues for you and your back.
I am fairly new at kiting and am trying to learn a few tricks. I have MUCH to learn, but have no doubt that the Challenger is up to the challenge and would be able to trick with ease!!
Good luck in your choice,
Lon
