It's quite funny that people say they only fly their kites for a short while 'til, "They get it" then they dont need it any more.
My experience is that most people continue to love their trainer foils and still fly them from time to time to sharpen skills and just to have fun. If you've ever flown a trainer next to a friend who is also flying a trainer, and had dogfights, chasings in the air, or tried synchronized kiting, then you'll know the fun you can have.
Trainers are also awesome for giving friends and girlfriends something to do on the beach while you're out kiting or whilst waiting for the wind to come up.
4-Line foils are a waste of time if you intend to fly full size kites on a control bar, although they will help if you wish to get into buggying, or maybe even landboarding if you intend on flying large 4 line kites on handles.
2-Line kites are fun but are more of a headache when you crash as you have to drop the bar, remove the safety, run to the kite, prepare the kite for a relaunch by setting it up again. Letting go of a 2-line throws it into death spins until it eventually crashes. In strong wind this can be unpleasant and usually ends in tangles.
A 3-Line kite as Steve said can be relaunched from the bar by pulling on the third line and reverse launching. This saves heaps of frustration and effort and makes flying heaps more fun. Self landing is also easier by letting go of the bar and the kite folds and drops immediately to the ground ready for it's launch.
A Small kite is OK for small people but larger bodies need larger kites. The smaller the kite, the faster and more furiously it flies which is not really like it's big brother traction kites. A larger slower foil is best.
If people outgrow and get rid of their trainer foils, how come there are so few for sale in the buy and sell? Spend the extra few bucks and buy a decent foil trainer like the Ozone Imps.
