wheels, go with the HPI MT Star (rears) they are cheap ($8 at HT) and good backspacing. If you are running stock tlt axles you may want to keep them stock width atleast until you get some wideners.

As for the ESC, I run the Mamba Maxx ESC and overloaded my BEC at the second indoor comp. Part of the problem was I had a mini Servo on the DIG (I still say your getting lucky Ponch). You would be suprised just how much juice a servo will pull when you are bound on a rock.

and as far as that Chassis goes....I need to raise the price on the Talon!!!!
