Does it change things that I play a tactical officer, NOT an engineering officer?
On a cruiser- not terribly much. You may want shields that have a higher starting capacity, instead of regen, but regen is still important. I tend to favor Standard shields (higher capacity than Regen or Resilient, higher regen than Covariant and Resilient), if all things are equal. Though if I find a regen shield with CAP bonus, that would find its way into my shield slot.
