So, I just read through the whole thread in a few hours (bless boring days at work...) and decided to finally sign up and contribute.
Some great stories and tips in here, I'll just add my 2 cents for a few things:
rigging up and tangled lines: firstly, wrap up your lines in a tight figure 8 around the bar and secure them properly. Will save a world of hurt. I run my lines from the kite downwind, then stand with my back to the bar, feet left and right of the front lines, but inside the back lines. that way, I can pick up all 4 lines, and have my legs basically separating them. Back lines run on the outside, front lines between my legs. front and back line of the same side in each hand. (I wish I had a photo, it's proving kinda hard to describe...) Then I walk towards the kite and the lines get magically spearated. If I hit a tangle, I put a hand out, palm up and run the lines in the order they will connect to the kite between my fingers and use the other hand to untangle.
The other thing I found really useful is to "deconstruct" the elements you are struggling with. Managing the board, kite, current, and everything else at the same time is pretty full on sometimes. so, if you're struggling to put the board on your feet, take the kite out of the equation. Sit in the water, put one hand in the air, put the board on your feet with the other hand, until you can do it blind.Yes, it will look silly, but it helps.
If you struggle with the correct board position for the water start, sit on a bench with the board on your feet, lean back and pull your legs up like you would for a start. Also a pretty good exercise for your abs, haha.
I could go on, practise the kite waterstart movement while bodydragging, or on the beach without a board (gently, so you get pulled on your feet without going flying).
So many things in kiting are pure muscle memory, I found this method has helped me a lot with the very basic skills.
Having said that, I'm still battling waterstarts, I can get up in both directions, but I have a tendency to go too much upwind too quickly and kill all my speed. And the worst about it is, I know what I'm doing wrong, but I'm not sure how to do it differently. Persistence is key I guess. Unlearning bad habits is definitely proving harder that learning something from scratch.
