Thanks for the tips.

My seat is probably in-between. It's not skinny, but I don't feel that it's too big either. And I am always standing on the downhills.

I think the practicing will help. I think I may need to just get over the awkwardness to be all the way behind my seat. When I'm headed downhill on singletrack, I usually don't feel like trying something new in my position. I think trying on stable ground will be a good start. I'll give it a shot tonight!

By the way, I earned my first medal (for 3rd place) at a mtn bike race this weekned, so I'm raring to go for more!

Thanks for the link to the other forum as well.
