You are in the modelling forum.... is this via modeler, software, or are you here in error and meant to put this in the amp forum? If you are looking to simplify/narrow down the options from a modeler I'd say your approach is correct. Get rid of option overload and narrow in on just a few. The choices however are very dependent on the styles you play. Another player might choose a Diesel, a 5150 and a REVV From your list, I would swap the Plexi for a JMP MV Lead (aka JCM800) just as a matter of preference.
