Just curious, whats the reasoning for 128th oz? Also what hook size? I often use 1/64th and 1/32 oz jigs (#2, 4 o r6 hook) with 2 or 3 inch plastics, and I've considered going even smaller, but I often wonder what's the point and why not just go weightless? A weightless Texas rigged or wacky rigged wiggly piece of plastic is my go to in less them 5 fow.
On a side note..seems like we're both really splitting hairs on tiny jig usage.
