Hi ladies-- I have a newbie question or two about mountain biking: Why would you change the seat height (such as examples of conditions and whether you have the saddle lower or higher for it, and why)? Also, I've been reading some pros and cons about going clipless, and wonder what you all thought?

I've been doing road rides (on a trek1000 w/LOOK clipless) for about a year now, and feel very comfy with it, and now some friends are trying to get me to try trails, too. So... somebody lent me an old GT hardtail w/platforms on it, and I've been experimenting a bit on easy trails. I was told that having the saddle lower (compared to the trek) was better for trails, but didn't really understand why. I just felt like I was wasting effort from a too low saddle... I also REALLY miss what feels like the stability of the clipless, but I'm also often glad I'm not clipped in while learning. I read this thread:

and I feel even more indecisive now, lol. --- anyway, any thoughts or advice would help!

Thank you!
