I'm a mid-cap player myself.
However, I've discovered in certain weather conditions, too hot, too humid, the plastic lower receiver will expand ever so slightly & my mid caps won't function properly - too sloppy, miss feed, etc.
I carry hi-caps to act as back ups & for those occasions where I may be called upon to act as the section support weapon (SAW).
