I used independent doubles to do a dive combining Angel City and the Hilma Hooker in one dive (my petite wife managed this on a single tank). This was a suggestion from Bas at Photo Tours, and it was a great idea. Swam out to the further reef of the Angel City site, then criss-crossed along it until a large chain appeared diagonally across the reef. Swam toward shore following where the chain pointed until the Hilma Hooker appeared out of the depths - awesome! The fish life & reef health of the outer reef at Angel City was very impressive.
