Any of those implants overcome the +1 TH from Void Sig?
Because . . . if my calculations are right, with a Clan XXL, iHGR w/2t ammo, Large VSPL, 2 Med XPulse, Small XPulse, 11t Ferro-Lam armor, CASE II, Void Sig powered by Clan ECM, and a single DHS gets a pretty mean Shootist firing from ambush. Not sure if a Clan XL & IS/CL Endo Composite would be better for crit/heat management but . . .
Its one expensive monster mech.
