I have found fishing the conditions your talking about 1/8 is usually pretty good but will go 1/4 once in awhile. Can’t catch fish if you can’t stay in contact with jig. Don’t think head makes that much difference if body size is right for what they are feeding on. Up here I use 1/0 and 2/0 hooks but down there I’d look for some jigs with #2 hooks where you could match with a smaller bait.
