I didn't notice in your post wheather you were looking for a solo or two up but I just put a LePera "barebones" on mine and it's definately lower and farther back.It's also allot more comfortable than it looks.I haven't had a chance to shoot any pics yet but there are plenty out there.

 

BUMP

 

I just got this mustang squareback, I also have the HD Touring seat. Touring seat is comfy but looks of it are not that good. Will prob try selling the touring seat before long

 

I went with the tallboy at first. It was comfortable but it looks like a couch. Also, it moves you up into the wind.

I currently use a Mustang Vintage Solo or a Danny Gray Weekday 2-up XL. Both are comfortable and move you down and back.

Most of thecompanies (Lepera, Corbin, and DG)will custom one of theirseats to your order specs - up, down, back, or forward.

 

I have the HD pillow look, sundowner or tall boy more comfy but I like the look of this seat position is slightly lower than stock no further back or forward
