Not to crazy about having a lure on the end of the line that doesn't have a hook on it. Looking at the double whopper plopper only the middle lure has a hook on it. I would hate to see a double digit blow up on one of the outside baits which don't have hooks.
If a DD blew up on one of the front baits he would have no problem fitting the whole thing in his mouth. They are not that big.
I have one in white and havent caught anything on mine yet either. Although ive really been waiting for the top water bite to heat up a little bit and I think it finally has.
