Well, I've tried the Lectric, Cloud 9 and, finally, the YLG seats. I've also tried the stock post, the Zoom and, finally, the Suntour SP12-NCX suspension post. I'm 71, 5'9" and 204 lbs and with the YLG/Suntour set up, am very comfortable for hours in the saddle even with ancient hip and knee injuries! I cannot emphasize how much more comfortable a true suspension seat post is over the shock absorber style.

Yes, the YLG and Suntour combo comes in at a higher cost (~$170), but it has allowed me to ride from a hour (max) to the maximum time the battery will allow!
