I already had a couple Angling A.I. 7'' worm molds and they work great in the Louisiana waters. I fished with a few guys last summer and they were using big 12'' worms so I gave it a try and I did well with it. I even caught several fish that were shorter than my worm so I decided to get a couple of the Angling A.I. big 13'' worm molds. I poured a few bags and they look awesome. I have a new big fish lure in my boat that I can't wait to get in the water this spring. Good job again Angling A.I.
