The Jodel is a TW machine so it will improve your flying. It will also allow you to explore the huge number of strips, which have sprung up. It is also capable of serious European touring 2 up with camping gear if that is what floats your boat. The main benefits are availability, you do not have to worry about the cost and you can fly a decent amount to improve. The numbers I quoted are based on a group which operates near my home base.
