Two jigs is more likely to hang up unless weedless. I’d rather use one, usually 1/16 but will go heavier if needed to feel the jig. Also the heavier the jig the easier to get out of a hang up sometimes because of the weight. If your not just letting the jig fall on slack line then the weight doesn’t matter as much as the bait size. Sometimes they like larger bait, sometimes smaller. Always try to keep tight line and feel of the jig and if deep water or windy then go heavier. I start 1/16 and go from there.
