I don't like the double rigs, too many tangles. I would probably use them where the law limited the number of rods I could use to 2 or 4. Here in the Carolinas, there is no limit and most use at least 8 rods. It seems to me that, at this time of year, the most productive rigging I do is hovering over brush. Since there is (ideally) little boat movement and since I have confidence that lighter gets more bites, the weight does not have to be very heavy. The heaviest I use is 1/2 ounce. I use a #7 split shot a lot. My rig is a standard Carolina rig. If I were moving fast in search of scattered fish, I wouldn't hesitate to tie on a 1 ouncer or even heavier. Good luck!
