On roads, I ride about an even mix of geared and FG. I can't decide which I like better....it depends on the ride, but this time of year I am usually more often riding my roadie long distances and working as many hills into the ride as possible.

Offroad I am about 75% SS and 25% FG. I don't have a geared MTB because I have never felt it necessary most of the time. However, some of the trails around here are really hard with a SS and torture with a FG. The older I get the more I find myself thinking about gears and suspension. Gears would also make it much easier to ride to the trails, rather than drive.
