I understand how you feel Dave, BUT Strike King and Luck E Strike have poached a LOT of lure designs as well. It doesn't make it ok that Zoom is doing it though.
Other companies are also developing that raised edge desigh to force more flutter. Keitech has one.
I really try to stick with the company that brings the better mousetrap to the market.
I have a bunch of the original Sluggos, BUT Mister Twister really did improve things by having a 5 inch bait that throws better and had the slot in the back which made it easier to get a hookset and easier to rig.
I still prefer the Senkos to the other baits of that design. I had to break down and get Barlows 3 inch rat tails because the 3 inch Senkos are just too fragile. I can easily fish thru a 20 bait bag in a couple of hours and catch maybe 20 fish on them instead of catching 5 fish or more per bait on the Barlows.
