Mine works pretty damn well vs pretty much anything, still upgrading and tweaking the missiles, but so far...

Assault Cruiser
Fore x3 Polaron Mk X Beam array, Mk X Quantam Torp

Aft: x3 Polaron Mk X Beam array, Mk X Quantam Torp

Consoles:
Tactical: All increase polaron 26%

Science: Shield regen 22%, Shield 35%

Engineering: All armor +22 (forget the names), EPS Flow XII x2

Shield, engine, and deflector are all Aegis set.

My ship at broadside fires every polaron beam, ducks back and forth for snapshots 1&2, and while dealing incessant dps, I am free to heal my team. All in all, pretty damn effective.
