Just received my mustang vintage solo with back rest and after installing it couldn't get past the looks. Imo a solo doesn't look like it fits a street glide. Really want a back rest so I decided on a c&c square back with back rest. When I called c&c they said the solo was their best selling seat and the square back was the red headed step child of their seats. They say most sales are solo and the fast back ,so looking for opinions from all who have a square back as far as looks and comfort,

 

I have it...not as good looking as the fastback...but it's very comfortable and the passenger part is comfortable enough for a full day ride. I'm not the type to keep swapping out seats. This one can do it all!

 

I also have one. I think its a very good seat.
