I better get off APC and do some reasearch.

No, 3b just means a DH lower than 50' or autoland and RVR between 150-700 feet.
3a is DH below 100' or autoland and RVR no less than 700 feet.
Using a DH means see to land, regardless of which approach you're flying. No DH=no see to land (but I think this obviously requires autoland).
No one from SWA has gotten on here and actually specified they fly Cat-3b or said what their actual mins are. Maybe that will shed some light on the situation.
