grump,
Sounds like you have pretty much picked up the same setup as me...
I went with the CRC 3.1 red after looking at the Corally SP12M and the Rev3...the Corally was cool for it's simplicity of setup...but parts availability seemed questionable outside of 1 local track here...and I have a preference of stick packs instead of saddles...even though the corally doesn't require a long wire..
The decision to go CRC over Rev3 was based on the requirement of purchasing tires...the CRC came with the proper setup for our local tracks, the lowered pods...to get more life out of the tires...and the fact that they greatly outnumber the Rev3's in my local area...so I get better setup and parts support.
Strangely enough though...the top drivers.....keep experimenting with different cars...new cars, old cars..lots of different things...and they're still the top drivers no matter what chassis they use.
I had a bunch of different people point me towards the JR Z3550..and that is the servo I ended up picking up...not too pricey..but performs well...I'm told (stil building my kit)...
