Did the same as well, could not be happier! Went 1300 miles last week (2 650 mile days) and body feels great. Just gotta set it up comfy from the start and quite a bit adjustment front to back and up and down.

 

.........and LOVE the setup....

 

I had the Harley adjustable backrest found it pushed me too far forward, also it is very thick and I didn't like the look of it on a streetglide. I sold it and bought a mustang back rest, it is super comfortable and adjustable up, down, and forward or back and it looks real good. Go with the mustang

 

Mustang Vintage solo w/backrest. Like sitting in my lazy Joe. I feel wonderful every time I get off of it on any ride over 50 miles (usually don't' us the back rest locally).

 

HD adjustable backrest with the Sundowner seat here, works great!!

 

There is another recent thread with a lot of opinions on this topic.

I also run a Sundowner seat and have had both the adjustable and the non HD versions. Sold the adjustable several years ago as it would not go back far enough. Just got the non-adjustable and took a bit of tinkering but have it where I like it now.

my 2 cents

 

After reading reviews I went with the Mustang for my stock low seat on my 2010 Ultra Classic. Very adjustable and looks great.

 

I got the standard leather backrest (used with the 2011 stock seat). I was unhappy at first but after some adjusting it is super comfortable. Just did a 220 mile ride this morning and I can honestly say I really like the backrest now.
