I bought the solo saddle and trunk from Billy who won it in the raffle at the F6B gathering this year.
Took me a few minutes to figure it out, but we're all sorted now.
The left saddlebag release doesn't function with the provided push tab thing on it, no biggie.
Everything else is on secure and the seat feels nice as it locks my tush in place - no more sliding about up that vertical angle.
It also puts me a bit further forward and my Kury Ergos fit better.

I didn't realize that the seat was heated. Major bonus.

Gonna take it out tomorrow and let my tush and the seat get acquainted. My Heritage has a Corbin which I like, so hopefully this will be fine too.
Not the best pic in the world:
