advise on a new seat
may want to search aroudn the thread, this is a pretty popular topic. I went with a sundowner, but mustang and corbing are also very popular. the benefit to the mustang (vintage solo) is that it is a one up seat that you can add a removable passenger seat to. kind of best of both worlds. I would have went with it, but the dealer said I could not return it and there was no where to try it out.
I'll probably go with the Ultimate shown below as soon as I get my first couple items put on. I'm hoping to add the seat by mid to end of September. Here's a picture of the full setup...

That is a 4-piece set (driver's seat, driver's backrest (pad and hardware), passenger pillion, and passengers backrest pad. Total price for the 4-piece set is $815, which is similar to prices for other complete sets.
You can get the 2 piece set (riders and passengers seat) for much less ($480), which is again very reasonably priced when compared with other brands.
If I don't go Ultimate then I'll likely go Mustang. I've owned 3 Ultimate seats and only 1 Mustang. I like Ultimate better because it fits my butt better and provides the support I like. The Mustang is good, though, and the bike I had it on was perfect for it. I could ride easy 600 to 800 miles days with either of these seats, but more importantly I can easily ride 1000+ days on the Ultimate with driver's backrest.
Here's the pretty straight forward poop from Ultimate on Warranty and Returns ...
