You have 8 wires and only need 6. So, just double (or triple if you want) up on the 22g and use that and the two 18g wires for E4,5&6 and A4,5&6. Those are the only ones going to the motor and the only ones needing to handle high currents. A/E1,2&3 only carry low currents for the positioning potentiometer.
Two 22g wires are approximately the same current carrying capacity as a 20g wire. Three would be closer to 19g equivalence. For short runs you can get away with a lot, but for longer runs, I’d go with the heavy duty line.

The Yaesu manual calls for six wires #20AWG each.
All the rotor control cable I can find at the usual radio stores is:
Standard duty: 2x #18 & 6x #22 @ $.049
Or
Heavy duty: 2 x #16 & 6 x #18 @ $0.89/ft.
My control line run will only be under 35 feet. Maybe I'm being overly cheap, but between the rotator and the M2 LEO pack, costs are starting to add up.
Your thoughts are appreciated.
