i love my 710 box stock its a winner, change the springs and its even better.

i was reading around the MyTSN website. and all of a sudden i see s710. is this just a car with more options? like that long servo saver arm and new adjustable diff collar? or does s710 merely mean Serpent 710?

sorry just not too sure about it.

anyways, how is that new diff collar and how do people like that long servo saver arm? ive yet to try them, but one of the hobby shops i go to normally showed me these new options, but i didnt want to buy something i mightve not liked. any feedback?
