    You could probably check the Airplane manuals – i’m sure most of them are available online….

    Typical, an elevator system will use a trim tab. (The Cessna & Cirrus) Typically, a stabilator system will use an anti servo tab. (The PA28/44)
     
    As for balance tabs, I don’t believe any of these aircraft do; though I am uncertain regarding the Cirrus. Do note, however, that the purpose of a balance tab is to give what is considered a satisfactory flight control feel for the pilot. On a stabilator system, the anti servo tab serves this purpose.

    The Cirrus doesn’t use trim tabs.
     
    From the SR20 POH:
    “Pitch Trim Control SystemAn electric motor changes the neutral position of the spring cartridge attached to the elevator control horn.”
     
    So adjusting the trim causes a spring to change the angle of the elevators.
