Hmmmm.. I was wondering the same thing, so I will definitely check this out. I am running (4) 0A versions on my Anaconda that are all using the Resistance Augmented mod. I chose this over the heavy duty version because of the added mass you get from the heavy duty mod.
I only have a Grade 1 upgrade on these at the moment since none of my unlocked Engineers provided more than that. Just unlocked Didi Vatermann and it looks like she can go up to Grade 5 with these. So... The timing of this thread was right on the money for me!
So far, these four identically updated SBs seem to do a pretty good job of propping up the Low Energy Modded 6A on my Conda, but obviously I would love to see even more benefit from using them. I hate being forced to run with a Shield Cell Bank on my ships since they really do a number of your jump range, but with a large ship like the Conda, once your shields drop, you are basically toast due to the glacial recharge rate.
I really hope the Grade 5 version of either of these upgrades perhaps will allow me to leave my SCB at the hangar bay?
