Personaly, I like the sound of the engine up front, once you get atuned to it, you can hit almost any RPM just by the sound. I've never cared for gliders either, even though there is a glider field less than 15 miles from my house. When I'm flying, I don't want to have to depend on thermals and wind currents to stay aloft, heck, I may change my intended flight plan just because.
