For realism's sake locaps are not so good, because irl a bullet would go straight through most of what we use as cover. Midcaps would be better for realism with about 80rnds tho, imo.
TM recoil mids is where it's at, you can switch them to 30 rds for when you play with people that use lower caps and back up to 82 when the high cap players come out
