I had Lee make my new image seat for me about two years ago and went to his house to pick it up... I just got a Corbin on ebay for longer trips and Im thinking about doing a comparison...
I only had the chance to ride my Corbin for a few minutes... but first impressions:
1.) Sits a little higher than new image... had more trouble flat footing with my short frame (5'8")
2.) Because it sits higher, my lower back ached immediately..but I think this is due to not riding for awhile.
3.) Very broad and stiffer, but very comfortable..
4.) The New image seat used to hold me in place under acceleration... I never noticed this until I tried the Corbin. I kept sliding back every time i punched it.
5.) I might end up using the corbin for long trips and the New image for the track.
