Found this on cruisercustomizing for $150. Looks like what I need for those longer trips, at a fraction of the cost of a Corbin seat & backrest. Found a few rave reviews on non-HD sites, but nothing on the fit or comfort of the Sporty version. Looks like it attaches to the top of the shocks, and has a removable socket-type base, which is good. For rides with the ol' lady, I prefer the D-cup backrest. :wonderlan
Anyone heard or seen or tried this gizmo?

Some folks from the other XL sites have these and they like them
