I have rode in and driven two different 35 twin steps. They are really nice and very fast.
One of the guys use to own a single step before and he says there is no comparision, that the twim step is all around better.
This is his fifth Fountain, 27, 29, 32, 35 Single and 35 twim step.
If ride is a real issue, I would look at not stepped. He cannot believe how much better our 36 Outlaw rides compared to his 35 Fountain. I cannot believe that with the same power he is 15MPH faster. It is a trade off.
Hope this helps in some way.
