Interesting, that is why I use 1/32 in the spring to fish around grass with out getting hung too much and I also feel the fish will hit the 1/32 oz. even when they don't hit larger jigs.
Also why I have added 1/32 oz. jigs with a #6 & #8 hooks. They are small (especially the #8 hooks) but look very good.
Wile your micro 1/64 is smaller, when they get this small I am pretty sure the 1/32 with a #8 hook will produce as well. I just a few days ago made up some solid Yellow Chartreuse ones to try. Also made a few in other colors, but the Yellow Chart. sure look good.
