Esshup, 1/100 oz? How do you see it?
I ate a lot of carrots when I was a kid!
I'm mostly fishing that rig in <4' of water, sometimes <2' of water, and I've found that over 50% of the strikes come on the fall as I pause the retrieve. The slower that it falls, the more strikes I get. If I use a 1/32 oz jighead I get virtually 0 strikes because I have to speed up the retrieve to keep the lure up off the bottom. The slower retrieve with the lighter jig head will keep the lure in the strike zone longer, getting more fish.
When the fish are really shallow, the lighter jighead makes less of a splash when entering the water as well, spooking less fish.
