I have used almost every style of Gulp!. I have found that some work better than others. The maggots are one of my go too baits in the winter for crappies and perch. I dont like using live bait in the winter (difficult to get in my area and keep, also i dont like reaching into water at -15C). I also use them in the summer for walleyes and honestly I havent been outfished by live bait often useless the bite was really slow and even then the ones I got, did hit with alot more force than just a nibbles, such as on the live bait sometimes. I love the sinking worm for bass, it is really heavy and I am impatient to wait for some baits to sink when I am wacky fishing. For trout I havent really done great with them and definitly have more productive baits in my tackle box. I think the newer line that they have is supposed to keep better and I know that the Gulp! Jerk Shads seem alot more "papery" and they tend to stay flexible and moist alot longer than the original Gulp!. I think there will still be improvements to this product as the research continues. I believe they will come out with a long lasting product line soon.
