Keeping the stock cERPPC, and keeping some nice cERML, you get a nice support mech. The TC1 or cAP could be used for some more DHS, but that's all build theory and testing. Weapon Groups 1. 2x cERPPC 2. 4x cERML chainfire
i would go this way: small lasers to get some DHS, so not much need for chainfire --> pinpoint lasers erppc counters ecm anyways, so 1 more dhc for the cap otherwise replace 1 dhs with cap.
Modern adaptation of this nice 'set of 8' build: _ It is hot, but you have the mobility to peak carefully (usually) and escape to cool off when needed. Also, the arm hardpoints are so poor that when peaking laterally you often are unable to fire one arm or the other, so that helps you focus on landing one or the other weapon. Primary weapons you should try to be working are the ERPPC's, the HML's usually aren't worth peaking alone for.
