Thanks, gents. I can use all the help I can get - riding on gravel and dirt yesterday was essentially the first time that I've ever tried it for a substantial length of time..WHAT A BLAST!!
I've dropped the pegs and put wider cleats on, but having some issues moving fore and aft while standing and riding over "whoops" (hence the query about gripping it w my knees, much like a horse). Pretty funny to watch me as the throttle went uP Down uP Down at the same time.
I did pick up Wicks&Baker's Adv Riding Techniques and the tutorial on standing in this section is a help, too.
Now for the fun part and off to practice some more. All suggestions appreciated.
