Yep, Put on a Roadsmith kit and absolutely hated it. Steering is extremely different, lost all sporty feel and mileage dropped 50%. I tried it for 6 months before I got so fed up I sold the thing and started over with another VTX. very expensive mistake.
If you want least cost route though, the Voyager kits are fairly in-expensive when it comes to an extra set of wheels and they're at least easily removable if you end up not liking it.
