I've seen people with this option also. Still debating getting a set of Gemini wheels and just store them for road trips, but kind of prefer to just run one set of wheels due to budget, and future costs (21" don't last long and are expensive to replace). Of course, switching to 19" tires will improve the ride, however minor.I think a good strategy is to get the normal gemini wheels and use the extra cash to buy second hand uberturbines. This way, you have two sets of wheels.
