Good question. I have the front and rear Traxxion, plus front brace, on my Wing. I really think it is a leap forward in the suspension arena for the Wing. I rode behind a friend on the Dragon (west to east) couple years ago who was on a ST, and he could not move away from me. He's a good rider, too. I did drag a few parts, tho.
Sooooo .... based on some threads on the 'old forum', I decided to purchase the Traxxion for my '10 C14. Figured that the Wing and the C14 would have similar responses.
As far as your question is concerned, go to Traxxion.com and see for yourself. I'm sure I would not be able to adequately tell you the differences. In addition, call Mike and have him 'splain it to you. He's the expert.
