I like the Shimano Soare Skiphead, the Diawa Daiwa Gekkabijin Salt Water light hook jigs, both at 1 gram. Lately I've been using the Eurotackle Micro Finesse Soft-Lock Tungsten Jig Heads. Also use the TM short shank and long shank jigs and tons of other 1/32 and 1/64 oz ball head jigs (Mr. Crappie, Arkie, etc). I catch fish with all of them, so unless I did some side-by-side comparisons, I couldn't say it makes much difference. The biggest differences in the jig heads is in the bait/lure keeper or the lack thereof. Some absolutely suck and I usually cut them off. Some work pretty well. But a lot depends on the plastic being put on the jig too.
