Well, gosh. I was taught to hold the seat with thighs if you have a FS. What you say makes sense, but now it is going to be icky to re-learn.

By the way, does anyone have pics of what you're supposed to look like when you're off the saddle? I learn well by seeing things...both demonstrations and photos. TIA!
