Hey Va,
I fish the drop shot 95% of the time however I'm throwing on spinning gear w/ 6 to 10 pound test flourcarbon line. Line twist is part of the rig but I found using the West Coast Tackle Quickdrop wieghts (Tackle Warehouse.com) will help cut this down without using a swievel. I personally don't like a swievel because its just one more area for failure when you hook a fish. As far as baits I love hand poured plastics, I only use Roboworms products. I have found they have more action and catch better quailty fish then injected molded plastics. Also be sure not to go crazy with hook size it kills the action of the bait. Hope this helps and tight lines.
