... using the 5th line self landing can be easy as pie and in my opinion easier and safer than 4 line kites with bridles. The only kite I use in 4 line is a Core kite which after a year of use, has never made me feel like its as safe or easy to land even though I haven't had a problem, its just that the Rebel or 5 line landing is sooo much easier.
I found that when I was teaching my son, I had to assume that he didn't understand a thing and I had to explain everything really simple which annoyed him but I wasn't prepared to compromise on a few things in kiting and one was self launching, self rescue and self landing. I feel completely at ease now and I can trust him (although he is a teenage kid and they seem to think on a different planet some times so a few choice words and threats of no kiting brings him back in line)
For me the following works.
1. If its windy, don't do this, check surroundings and punch out at waters edge making sure no one/thing is downwind of you.
2. Pick your spot and check where your landing and a big arc downwind of you for any obsticles.
3. Kite at 12 o'clock, pull depower fully and don't pull it too fast, nice and slowly.
4. Steer and drift kite down to ground at the edge of window, slowly.
5. As the tip just touches ground, reach up above the bar for the red line, let bar go and pull the red 5th line in quickly, pulling in 2 or 3 good arm full of line.
6. The kite should be on ground, run up and secure kite. smile.
I can usually land a kite in good winds and exactly where I want to, but on the rare occasion, it can slide down wind but since you have pulled in the 5th, it won't fly again. If windy, just keep pulling the 5th, it will, or rather should, not allow the kite to get out of control, that's why you pull it in really quickly. Commit to pulling in the 5th line, quicker the better, this pulling in yanks the kite forward and the wind pushes the kite to the ground and pinning it down, but, be careful in windy conditions 'cause some times they can slide.
I hope this helps a bit!
cheers,
Robbie

ps I got a wife who does that too me
