I fish mine a variety of ways. Sometimes 3/8-1/2 oz with a rage craw hopping, dragging, and dead sticking like a jig, sometimes punching through grass with a 3/4-1 oz, sometimes swimming it around with a paddle tail shad, sometimes with 1/8th oz and a roboworm like a dropshot.
They are very versatile and effective. They slip through grass easily, they rarely get snagged, and they cast further than most rigs. They aren't a t rig replacement though. It just depends on the bottom, structure, and mood of the fish. Sometimes the bait chasing the sinker down is the only way to trigger a strike, but sometimes it's the subtle dance of a jika on the bottom and in between rocks that triggers one.
