I test rode a Rocket 3 a few years ago. Seriously impressive performance and the weight just drops away once you are moving. Also considering the huge size they handle very well.
Having said that I didn't buy it because I just couldn't like the way it looked and to be honest I really didn't need anything that fast. However trying one out was an itch I had to scratch.
If the Thunderbird had been available then I would have considered that. Love the way they look and absolutely everyone I have spoken to who owns one of them has been impressed with both the perforrmance and handling.
