I got a Peter Lynn VenomII 13 four weeks ago and just walks all over the inflatables for beginners and experts alike. It has so many advantages:
1. self inflating - no pump needed
2. self launching/landing - no assistant needed
3. very very stable at depower/idle - no need to watch the kite - it just sits at 12 OClock all the time
4. very tight turning - excellent in low wind.
5. Very easy to relaunch from water crash - and unlike inflatables will not crash if one edge hits water - very forgiving
6. will not suffer weakening from wind action when parked on the ground - very long life kite
Only a few disadvantages:
1. Can luff in waves - not the best for beach kiting
2. Needs to be got out of water within 15 minutes - wont float forever like inflatable
3. "bowties" easily, but with just 4 lines its fairly easy to unbowtie it once you know how.
No kidding this is a kite that will last you for many years.
Oh and BTW, I'm from a waterskiing background and I never had a lesson (just watched videos & listened carefully to good advice from others).
I've post edited this (above) because although its true its a reckless comment to make.
Unless you dont mind risking serious injury, get lessons. This sport is potentially, extremely dangerous. I regret any offence to instructors.
