Yes this is what I have been using also . White Tube jigs around 4 -5 inches long tipped with a minnow ( 2oz weight inside)
I just find most lakers last few year do not not want to take bait that big any more ,as they are full even before the sun comes up.
I was in 95 ft of water last year and my LX7 screen started show very large groups of bait fish that would fill the whole screen ,i mean from the top down to 95 ft . I thought something was wrong with my LX7 ....but I looked down the whole and it was full of bait fish about 5 inches long .
So I need to slender it down what i but down the hole.
Been getting harder to catch a keeper as they upped the size at cold lake . They now have to be 29.5 inches long, and you only can keep one.
Takes me 3 hrs to drive to this lake and i just want to bring as much as I can to test what they are biting on.
Fishing this lake more than 20 years some winters you catch 10 and one is a keeper. Now you catch 3 and none are keepers.
They are just full ,but still like to chase !
