Joe, I had the same thing happen as you. Stripped harnesses or just the tails of worms nipped off. Weight of the fish there then poof, gone. I can only blame myself for that though. These eyes were hitting very light and swimming with the boat. I should have A: sharpened my hooks better. And B: added small treble stingers to the last hook and into the tail of the worm. Every eye we landed saturday was Barely hooked in the tip of the mouth with the last hook. Not one fish hit and was hooked solidly. Also none of the fish tripped the dipsys or riggers. I was running snubbers on everything, but also had everything set very light. Makes me wonder how long those fish were on? Cause everytime I would check the lines I had walleye on. The only time my lines popped was at the very start of trolling, both riggers popped within a minute of each other the first ten minutes of trolling. Both lines had good solid weight on them half way to the boat. Then gone. And what's with the small fish this year? I never used to get small and big fish mixed while trolling open water. Usually smaller fish would be in the shallows. By small fish I mean you have to question yourself about getting the ruler out to see if it's even legal and just end up throwing it back anyway. Lol
