Advice / tips to target halibut off La Jolla

[Irishman]

I'm hoping to score a nice flatty tomorrow. Yellowtail and sea bass steaks are in the freezer and my better half likes halibut. I normally fish the three way swivel on the bottom for the flat kind. Are they biased towards a specific bait? I know the yellows I caught were all on greenbacks. Do the Spanish macks work for halibut or are the greenbacks preferred?
I plan on yo-yo'ing a jig for yellows and flyling a live bait. Then for the last two or three hours really trying to target halibut, hence the bait question. Any and all advice welcomed as well as anyone who wants to paddle tomorrow morning
Cheers
