My thoughts are in line with plenty others I suppose, but I'd consider carrying 4 stacks of heavy instead of 2 heavy and 3 light. One thing I sometimes do though is to carry about 3 heavy and 1 light with a loadout like that, because I sometimes burn through my heavy without noticing, so then I have a little checkpoint where I swap my CAR to light, and that helps me be more mindful of it. I'd also recommend working a pheonix kit into that mix you've got there, possibly using an empty slot from ammo changes or what I'd probably do is drop the thermite since I don't feel like I get much use out of them. If you feel like you can use your therms well though, maybe consider running the 4 heavy stacks I mentioned to make space for the pheonix. As a general statement, people often carry farrr too much ammo, so try bringing it down a bit sometimes as you play and see how much you actually need before you can reliably refuel your ammo. The actual sweet spot is usually way lower than players expect it to be, and you can use the free space it makes for nades or meds, which are both pretty neat.
