Just picked up a Mustang Vintage Super Solo (79446) with the backrest and it's awesome! I had a Saddlemen Road Sofa and it was terrible. Not sure why it didn't work for me but it was exhausting to ride on that. The Mustang is incredibly comfortable and the added backrest for an additional 140 bucks is great! I think I could ride this thing all day and dammit I'm gonna try! But seriously, if you're in the market for a solo seat, this is a winner for me. Got it at Direct Cycle Parts...no one can beat them, man.
