I get it. We all dial tones in differently. I have never found an overly mid-heavy sound sits well in the mix, but that has been my experience. I always gravitate towards tones like Clayman, Heartwork, Nymphetamine, Shadows Are Security, None, etc, never like Fluff's, so I always dial in my tones for them to sound good mic'd and in those kinds of mixes. But I honestly don't have a problem getting those tones to translate well to a live environment. I mean, after all, when you blast 90's/80's Metallica through PA's, the guitars never have a problem cutting through, do they?
But to say mids is the only way to go, and I need a nice fat blast of midrange is taking it too far. If mids work for you, all the more power for you. But I honestly thing that's a more recent approach to dialing in tones that I don't like. And that for many people doesn't work either, many much more experienced, knowledgeable, and with a more professional approach than me.
