125.85 IS ACTUALLY A BACKUP TO 120.85(SW DEP TRACON ). I think in my opinion the second feed should be of 128.55,120,15,and 125.5(final) . 125.5 is used for final in conjunction w/120.15 mostly. 128.55 is usually the final for runway 4 landings. Flow is as follows if landing south 128.55-120.15-125.5/120.15-125.5(west and north arrivals. Landing north is 128.55 to tower and sometimes 125.5 as final and 120.15-128.55 for west and north arrivals
