I have the custom leather Brawler on my '08 NT. Like brett said, it's pretty close to the stock Badlander. I measured .5" further back and exactly the same height. It works real well for me, but it did take 500-550 miles to break in (dunno if that's because of the leather or just a "new seat thing").
I have a brand new Brawler solo seat that was on my x bones when I bought the bike the my dealer gave me the stock seat to put back on per my request. I have not used the Brawler seat and would be interested in getting rid of it. I've got a brand new x bones I've only had for about a month. I have pictures of Brawler seat. If interested pm me.
