I don't see the need to get a FT TC4 right away. I have been racing my Team TC3 since they came out and havne't seen the need to make it lighter. In fact, I also own the racer version and like the composite axles more than the aluminum ones. A FT version may represent more glitter for the dollar, but I don't see that it gives much of an advantage unless you are driving at the Barry Baker or Masami level.
