IMO beamoverload3 misses too much. and with all those beams you got on your ship you might not want the sudden and revolving power drops by running 2 overloads. even if you run weapons batts and red matter capacitor and such.
i think you get your best spike as a tac in excel when you sandbag to 40% hull or so then harden it with say...Brace for impact and Polarize hull...and aux2damp. then get the max out of stacking Go down fighting (by not healing hull, just a 15 second hardening) APA, APO, FOMM, TF. make no bones about it you are a tac cruiser and go down fast without support. i played defensive 75% of the time using a 6 array 5-7 click broadside suppression at a slightly lower weapons power between spikes.
mavs advice on high cap resilient shielding works great with this idea, as it lends to limit bleedthru.
and id run at least a neutronium...although spreadmania has me slipping in the monotanium lots in my cruisers lately. gl with your build man.
