Could it also be that you're in too high of a gear when starting off from a stop? I tend to do this all the time....grrrrrrrrr! As I approach a stop, I forget to shift into a lower gear to make starting up again easier. BTW, I also start from a stop with my butt on the seat and tippy-toe (right foot only, left foot clipped in) on the ground. But as long as I'm in a lower (easier) gear, I can generally get moving pretty quickly. Just a thought...since I didn't see anyone else mention it.
