I believe you can run the following set up with the HFS-6:

1. Water two smaller jet will be enough, (0.4mm + 0.5mm)
2. W50:M50 two jets and a mild tune (0.5mm + 0.7mm)
3. 100% methanol two largest jet, a more aggressive tune. (0.5mm + 1mm)

I think you should start with "1", good safety and no tune is necesary.

The HFS-6 is very flexible, as long as you use a slightly larger jet, they you can reduce the flow electronically.

One small jet before the IC and a bigger one after the IC.
