If you got a masc, might as well get all the mileage you can out of it Also, you really don’t need 5 tons of ammo
While I am a fan of LPLs, LLs synergies better with MRM - both in range and duration. The shorter cycle time of the LPLs will often be wasted when waiting out the MRMs cooldown. I would tend to go with LLs and use tonnage to maybe squeeze in MRM30+20? Not a fan of MRM40 due to the larger spread and longer cooldown.
I already tried the 30+20mrm plus LL and it has a lower dps, plus I’d have to disagree on the range, firing the mrms at longer than 400 is a waste cause somebody’s bound to have ams, and unless they don’t move, your going to miss quite a bit more, so I’d say 350ish is more in line we’re you want to fire mrms anyways
I run something similar to 2xLL + MRM50 on a different variant of the Zeus. It's not great but it's not bad either
