Hi,
Beats me why there isnt a sticky about trainer kites, as this "which trainer is best" comes up very often.
I have tried quite a few and still carry 2 in the car with me at all times (ozone imp & an ocean rodeo rise 2m ).
The imp is the first one you give to people who have no idea what they are doing, as mine seems to be indestructable, and once they are ready to move onto a 4 line kite you pass them the rise 2m.
The three lines makes the imp extremely easy to relaunch, but the rise 2m relaunches the same as any 4 line full size kite, and therefore takes most people some time to master. I hope this info helps you make your choice.
note - I dont sell either of these, and im not some sponsered rider - i just fly for fun
