If your bank account can handle it, the next logical progression would be to something like a Focus Sport ($295 from Central Hobbies). Your YS 110 will do well in it and it flies a lot closer to modern pattern planes than the Venus II. If you decide to go that way, follow Troy's thread on setup and you should end up with a good competitive plane through Intermediate if not Advanced.
This is one of the things Iwas hoping to talk about. Is a plane like the Focus Sport really that much better? What is it about planes that make them 'better'?
