I would think there could be numerous reasons why you lost the fish, with the jighead being one. I use weedless, have lost fish, but the typical reason is the “junk” that caused me to go weedless to begin with (limbs to wrap and pull, etc). I’ve also lost them on non weedless heads. I like a #2 hook. Yes, it is more likely to hang, but also more likely to hook in the roof of the mouth.
