It's all so subjective too. And it's also always about the run and about the individual mold. I have a Med Electron from about a year ago that is really stable, more than most of my premium Envies, and it's got some chunks out of it at this point. It's also much firmer than the old Med E was. My old Med E is really beat and US, and my old Soft E is beat but still moderately stable. Sits between the two others. But those are mine, and from the specific runs mine came from. YMMV.
