Hi, Mouse42. I'm always so impressed with how thoughtful you are in all areas of your training!
I don't have any experience with treeless saddles other than riding in one once earlier this summer. It was a little strange at first because you do almost feel like you're riding bareback. However, after I got going, I forgot about the saddle which I guess I wouldn't have done if the saddle got in my way.
I'm going to pm you the name of someone who's close to you (I think) who uses one so you might see if she has any info to share.
