You can always toss tweak the ton gained from the Endo Armor but it is negligible in my eyes. I put it into another DHS but you could switch out Artemis and add another SRM launcher, etc.... Overall I prefer the clustering of the SRM4+A and with the current setup it is cheap and runs cool.
Went all the way to elite with this setup. Dual ERPPC runs too hot for me, and SRM4+A work at both range and CC. Love this mech.
