Actually, for plain bait fishing for Halibut (No flasher) Sardines are numero uno and Squid is second. Except where the Squid are, or have recently been, spawning. My most active day with a flasher so far was with dead Sardines too. Sardines have to be 7 inches or bigger, or I will opt for a different bait. Squid has to be live or freshdead, or I will opt for another bait. That is what works for me, but individual results may vary
