I put in a lot of work on the ProSC/Prolite chassis. Very underestimated and with a little work will surprise all the big boys. Go over to the ProSC thread, grab a coke/beer, and read it through. We've covered pretty much everything soup to nuts on that truck and the info you get from that thread will set you up for success with it. I've run it back to back with my SC10 4x4 FT, on tight layouts it's a wash, but on larger, flowing layouts I'm faster with the Pro.
