I'm surprised to hear that the Rocket is selling well. I've yet to see one on the road. But, then again, I do live in the sticks. I sure hope they look better in person. I'll take the new ST, thank you very much.
I've ridden many enjoyable miles on bikes that were less powerful than similar models offered by competing brands. I tend to use the smiles/mile measure as opposed to horsepower/cc when I consider motorcycle ownership. But, I have a feeling you've been there too with a name like Tigercub.
