Fishing bass tournaments, I have found these hooks to be one of the best hooks I have every used. They work great for Tube baits and hold the tubes in place even after several fish. If they tear out of the tube you just turn the latch around to a new spot and re-hook it to the tube bait. They are extremely sharp. #1 seem to work fine for 3" tube baits and can be rigged as weedless by not inserting the hook all the way through the tube bait.
This is by far and away the best tube hook on the market today. I use a lot of tubes and various other soft plastics and this is a great hook. It will not let your bait slide down the hook at all. Even when you do catch a fish on one as soon as you take out of the fish's mouth it can be thrown back into the water and fished. It is an amazing hook. Very sharp as well.
