Mate if I am not mistaken I sold you my (blue) Zephyr at a good price perhaps 1.5 or 2 years ago. You kite at Pengos, lately more at the blue toilets. Some of the folks kiting at Pengos consider you being a bit of a grumpy misfit at times
Happy to pay attention and give you a few pointers next time I see you. Don't waste your money, it will be a free advise. Done it heaps, happy to help. Pretty sure I will be able to advise what is wrong with your landing technique.
Last time I saw you you tried to practise your low end on a sb. Seen you in lower winds on larger kites most of the time. A higher wind / smaller kite day may be better for proper vertical jumps. Better for actually going fast, moving the kite quickly hence reaching good heights, giving you enough time to prepare for a good landing (I agree with Lambie a lot of kiters I see just don't land facing downwind and hence crash or come to a stop), and kite will be fast enough to be redirected quickly when you need it.
Anyway, say hi, smile, and we'll sort you out ;-)
Cheers,
Andy
