*applause* for using this mech the way it was designed to be. I dunno about putting tag in the arm instead of the head and ammo in the ST's, but I like the look of it - you're making it unique to other variants.
I would rather put an AC10 or Gauss rifle, but the SHD can to it better. I just wanted to see if a long range HBK Grid Iron would even be viable. My thoughts were that the Ballistic side would get shot first, so losing the TAG might be bad. But this thing HAS to be able to zombie with it's STD engine, otherwise I would have run an XL engine and not given a care to where the TAG was put. I'll put up an XL variant as well.
