I use the foam ones like the four you have on the right of the picture pretty often, depending on the size of jig head I'm using, but I probably use the Thill slip bobbers the most because of the times when I have to cast into a small opening in the duck blinds I fish, where the water is 6-7' deep, and the fish are on the bottom. The ones I use have the little brass opening attached on the top, though, that allows you to slip the line through the bobber.
