Rogue MegaWatt 30Amp bulk charger.
Been using my Megawatt 30 amp PSU now for over a year with the fine adjust pot, when mxwanderer suggested a 500 ohm 2 watt 10 screw potientiometer to replace the rather touchy one screw micro pot. ...

I wouldn't call it a non-issue until you've verified the output has no excessive ripple. You can't see that with a dc meter. You need a scope set to ac and 200 mV/div. If that's flat, THEN there's no problem.
I am going to assume max ripple at max watts. Some data was provided except for your thoughts regarding max permissible ripple in relationship to near perfect <2.0 MV. You wrote you specialize in power supply design. So surely there must be a worry-point with regard to ripple on this section of the circuit.
Yeah I have to play 'Fraidy Cat because of where I live. In theory a strong bolt of nearby lightning can influence a hypersensitive circuit. So call me chicken. It depends on Salvo's answer. Max mv ripple permitted.
Might as well buy a couple of meters of shielded pair wire. Don't forget Niner your plastic rheostat itself is a coil subject to inductance. I have seen bad juju results of circuit resonance ringing and I ain't too keen on shortcutting and getting whacked by an inside straight.
