Manta Ray, Top Force standard or Evo WHY?

[FERRETTI]

Looking for a great runner condition Tamiya Manta Ray rolling chassis. Modifications such as ball raced, ball diffs, Hi Caps, RW chassis, UJs are all desirable WHY?

Or an equally nice runner condition Top Force or Top Force Evo rolling chassis

No radio, electrics needed/wanted, condition of body irrelevant.

Thanks.
