I’ve been using a NeoMag for a little over a year, usually in my left back pocket. One of my ECQC realizations was that changing mags in the middle of the fight was a death nail. Moreover, while I still want a spare in case of a mag-induced malfunction, I realized it didn’t need to be forward of my hips, nor did it need to be on the belt at all (thereby minimizing weight on the belt).
