nope, that one had dual SSRMs. i don't know how they obtain the tonnage for some of the builds(and i don't mean just the hawkmoth D, but also for example the Hollander II E).
You forgot BAP. Any ECM mechs would essentially shut your down from doing anything the peppering them with some MG fire. Honestly I think this is the best "pure streak" build you're going to get with Kit Fox. 3 tons of ammo just doesn't cut it.
I run 4streak 4 and a beagle Make sure you have a beagle and 4 streak 4 is still enough to kill an oxide! Who has to give up speed or armor to even be able to barley have 4 tons of ammo for his 4 streak!
