So in the last patch AC10s became one of the most useful ACs, and SRM2s got a huge cooldown buff. Chainfiring 4 SRM2s is perfectly aligned with these new cooldowns so they can be used as a close range harass and are a more powerful than the machineguns from the JM6-DD build with 2x AC10 (though less DPS/tonnage). Hit registration problems with SRMs are fixed on april 28th and only occur when there are a lot of explosions to calculate, thus is mitigated somewhat by having tiny launchers. You can swap a ton of SRM ammo for AC10 ammo, if you find yourself hanging back more (90 shots is definitely a nice upgrade over 75) Also you can swap AC10s for LBX10+ML each. I advise against swapping the DHS as AC10s+ML and then mixing in SRM2s will get very hot. Not a gamebreakingly different build from the streaker builds for this chassis, but no lockon required and ability to fire on a certain component is nice if you have the aim for it.
