I've been following your posts and your bunny hopping woes.
The Bruzza will suit you fine! Sure, it's more bike than you need, but it sound like you'll improve quickly.
Best way to get better fast! Ride with people who are better than you and watch how they ride. Shift when they shift, follow their lines, ...etc. Don't be affraid to ask either. Most people will be more than happy to give you some tips and tell you what they do!
Really, you'll improve 10x's as fast by riding in a group vs. alone!
