Not sure if you're on a budget but you can add Endosteel for an easy 5 tons and Swap one ERML for another LL and another DHS. And as a personal preference, I would dump the AMS and shave a little armor to add a JJ. That actually lets you get Light FF and gives you another full ton to work with.
Max cooling version, so in the skill tree you can avoid heatgen nodes and focus only on cooldown. _ EDIT: you can easily get max speed tweak and max seismic sensor, while retaining full range and almost all armor nodes https://kitlaan.gitlab.io/mwoskill/...c62101cf37f000000000070a5fa10000000#s=Weapons
