Running a vulture with 2xC3G beams, A rated power plant but stock 5E shields. Is it worth upgrading the shields? The power draw seems to rise significantly as the rating goes up - is there any noticable improvement in shield durability or am I just asking for trouble in the middle of a firefight? I've seen the formula that's floating around re mass etc but to me it seemed rather inconclusive. What's people's experiences?
