I had one for a while I really liked it. It sat me up a bit higher than I wanted. I am thinking about trying the new version which is supposed to sit you lower.
I love mine..... only had it a month so no really long rides on it yet, the longest being ~600 miles in a day..... no aches, no hot spots, no sore butt.....
I have two of them. One came on my 2009 CVO Ultra which now has 18,500 miles in the past year and numerous back to back 400-500 mile days. Most comfortable seat I've ever had in over 1/2 million miles of riding so I bought one for my 2010 Road King within a couple of weeks of buying it. One note is that it does not provide much back support without a backrest. If you get one I highly recommend a backrest. It also sits you a little further back from the handlebars and is pretty wide. I'm 6' 2" tall. You may not care for the height and width if you are under 5'8" or so.
