My frustration with the MVP mids is the gap between the reactor and hex isn't enough IMO...at least for me. Reactor seems to want a more pronounced 'S flight' as it breaks in compared to the Hex being a laser beam. But for me, I'd ideally like to have a 5 5 0 2 that i could beat into something straighter or having a bit more flex to it...like the mustang or kotuku...i've just invested too much into MVP right now to make a switch. Eclipse reactor - fission reactor - fission hex isn't a bad shout by any means.
The Plasma Pyro's close to what you're describing, I think. The main reason it's out is my irrational commitment to symmetry and wanting three 5s and three 6.5s in the bag.
Right behind that though is that EVERY time I try something other than my non-swirly Resistor for an escape shot (where I'd be most likely to deploy the Pyro) I end up having a firm conversation with myself about how ALL escape shots are Resistors. Player one or two doesn't matter. Whoever's got the pink has it dialed. So it's also somewhat about not leading myself into temptation, to borrow from the liturgy, and keeping the options intentionally limited to the best one.
