Yeah, solo landing tubes is a pig. I know guys reckon it's no worries, fly to the edge, turn down quick and pull the safety line, attatched to the upper wingtip, but this method is really dangerous. Sounds like going to safety is dangerous to both you and your kite.
I've got a solution.
Sell it. Buy a flysurfer!.

I kite solo a lot, one of the attractions is really easy, quick and safe solo launch and landing. And the hangtime......mmmm.....floaty..........
