i have used both but never together.i guess it's as close as u can get around here.
For gearing,if u're using rubber tyres on asphalt:
try 6.8-7.0.no need to change the gearing if u're switching between profiles.
I'd say pink front and blue springs rear.30wt oils.I hope u have the rest of the setups bcos that's all i can remember.
I suggest getting a Hotbodies upperdeck or HPI upperdeck for better response.
As for the BL,dont worry if u get thermal shutdowns.try using a fan(5V) on the ESC.
