Well, I have to chime in here. Jim installed my Traxxion kit yesterday evening. I was prepared to be disappointed as I was sure those spending the bucks for the TD cartridges would never say the money was wasted, even if it was. Goodby mushiness. Goodby front end dive on braking. Goodby the vague feeling in the front end when cornering. Good by the bone jarring klunks when you hit an unexpected hole or bump. Etc. Etc. The front end just feels more precise. As far as I'm concerned the Traxxion kit is a must, especially for those with the '05 front ends. My wifes FLHX alway seemed more precise than my SEEG. No more. The difference was noticeable in the first turn. The bike also seems more stable at extra legal speeds. Don't get me wrong, I'm no speed demon in the North California twisties but I picked up several mph through the really tight stuff. This kit really does work. You will not be sorry.
Thanks to all who posted earlier with their experiences. And a special thanks to Jim (hd-dude) for dealing with my wife and I for 4 hours while trying to run his business. If you are in his neighborhood you couldn't go wrong with asking him to work on your bike. He's going to be working his business full time ( I hope I can say this) so send some business his way.
