Well I ended up getting my Fargo, and got the 2, which I didn't realize had a thudbuster. I ride a B17 on all my other bikes, but before I ordered the bike I got a great deal on a B66, so now I am not sure which way to go? I think a thudbuster and a b66 are a bit too much. Anyone try both before, and have an opinion? I've never done a thudbuster, or a sprung seat, but since I plan on mainly gravel or off road touring I thought one or the other would be a good idea.
