Anybody with a Blackline or Slim that's got the Mustang Wide Vintage Touring seat care to weign in on it?

I have a '13 Blackline with the Tripper right now, I like it, but my lower/middle back starts really bothering me after 2-3 hours in the saddle, and Id like to be able to ride longer than that without pain. I want something a little thicker and wider with a back rest, so I'm thinking about the Wide touring with the driver backrest.

 

Anyone?

 

Has the optional backrest. From the get go took the pressure off the back bone. On longer trips I use the backrest which keeps me in the same spot because with the apes the wind tends to push ya back farther and farther. With 1500 miles on the seat it's increasingly better.
