The SC10 body will fit, but as TAC said- the Blitz body is nicer looking. Also, the angled, "nose down" design of the front end helps the trucks to jump more level.
As for wheel options, the Blitz uses the same offset on all four corners. This offset is the same as 2WD rear Slash wheels as well as 4WD Slash F/R. If I'm not mistaken, the new Kyosho truck will use the same offset as well, allowing more wheel options yet. Personally, I would use either J Concepts or Pro-Line wheels. They are made without the "step-down" from the inside to the outside of the wheel, allowing the foam to be more consistent inside the tire.
From what I have seen, the Blitz is slightly tougher than the SC10. My SC10 held up very nicely when I raced it though. Both are solid trucks, you will be happy with either one. If you only have one LHS, I would buy whichever one you can find parts easier for.
