Ok, these numbers in from lord_leperman: (thanks! I'm in the office. XD)
L x H = Area (in centimeters on Leperman's TV)
Locksizes:
VOLUTE 2
ST + ST = 20 x 22 = 440
ST + ND = 16 x 17.5 = 280
F73H
ST + ST F73H = 25.5 x 15.5 = 395.25
ST+ ND = 22 x 13.5 = 297
LIMPET
ST + ST = 22.5 x 25 = 562.5
ND + ST = 18 x 20 = 360
Ranges -
LIMPET
ST + ST = 306
ST + ND = 310
F73H
ST + ST = 391
ST + ND = 409
VOLUTE2
ST + ST = 345
ST + ND = 429
Conclusion:
LIMPET definitely gives a huge box. But bad range. For the rifles, that's ok. But it hurts the geryon a bit.
F73H and VOLUTE2 are sort of tied.
So... my conclusion is that I'm more confused now. FCS choice will depend on how the AC will be played.
EDIT:
VOLUTE locksize
ST + ST = 19.2 x 21.2 = 407.2
ST + ND = 15.7 x 17.5 = 274.75
