1/2 ounce weight stay under .5.
If you want to push at speeds up to 1.2 mph like you do long lining 2 ounce weights can keep your jig in the strike zone.
This time of year I push double jigs on a 2 ounce drop shot rig or double minnow rig up to 1.2 and the bait and crappie yesterday were from 4 to 7.5 feet deep over 25 FOW and this technique worked well.
With rods that can carry heavier weights pushing you can also pull jigs at the same speeds and do both techniques at the same time from the front of boat.
