I've got a lot of "hope" built up in thinking the Mustang saddle will be the right saddle for us. I've got a stock rear shock link coming so I can get the ride height back to stock, as the lowered link thing ain't working at all. Might have to visit Traxxion Dynamics for the rear shock NOW and will decide if I'm all in for the front end rework after 6 months. Our Road King is still the default for touring, but my wife is definitely loving the big Honda.
Thought about the BMW 1600B, but having ridden BMWs for a few years, not sure it's in the sweet spot for us.
However, in the mean time, the F6B is definitely meeting all of my expectations.
I should note, my last Honda was a CBR1100XX and the F6B is 15-year old version of the same bike!
