I am not sure on the sizes, but I think I have them from 3" all the way up to 5". I have had various brands .... Chompers, YUM, GYCB, etc. Don't really have a favorite.
I use jigs from 1/8 oz up to 1 oz. I use the hula grubs on them all.
I don't think I have ever thrown them alone. No reason. It's just if I had the option to rig them on a jig or use them alone, I would always pick the jig. I like bulkier baits.
