By all means use a corkie for drifting S.Shrimp.
By useing this you will elevate the float through the strike zone,increasing your potintial strikes. I have had good luck using whole shrimp with a double hook set up, and double corkies.That said this set up was used mostly for summer runs as they are a little more aggressive. You can definetly try whole for winter fish. As for corkies stick to smaller sizes and consider useing pinks, yellows, orange, and other colors that contrast a S Shrimp, yet still stay close to the color sceme of a S.S.. (as shrimp will have splashes of these colors in them.) Good luck and Many hook ups to you!!!
