Hi there frostyballs,
There is not a thing wrong with learning on a modern Rebel. Puppet, better to comment only from first hand experience eh

The North kite have the best safety system in the business, they are as stable as the best of them. You have the ability to slow the turning down dramatically with the back steer line adjustment and smaller width setup on the bar. They have good power and are made of the finest materials which means it will be flying long after most other kites have stretched, torn and fallen apart.
There is a good reason Rebels sell more than any other kite, it's because they are top shelf and suit everyone from beginner to advanced freerider.
