Former UCSB Golf Teamer here:
Sandpiper, spendy but about Torrey Pines quality, not Pebble.
Glen Annie, boring and contrived.
SB Muni, worth playing more than Glen Annie
Rancho San Marcos, prettier than the shot quality is good. overall, worth playing.
For a KILLER golf EXPERIENCE, drive NORTH 45 minutes up into wine country and play BOTH Marshalia Ranch *former Vandenberg AFB, and La Purisima, beautiful and very good quality golf.
Marshalia is a classic and feels like Carmel and is waaayyy under-priced.
