Obviously my choices for the MCC004 would include the lovely 4163B :D.
I've also had good results with the MCC004s at 8x-12x with:
Sammy 203N (your drive + LS as you know)
I also loved my Pio 115D for 8x MCC004 burns, but sadly I no longer have it and it's not available now :sad:...hopefully your 112L is just as good though, as people have suggested.
Can't speak for MCC 03RG20 as I hardly ever use it.
