Wasn't it really windy out on the lake yesterday? I know for myself, if it is really windy this time of year, it makes it tough to fish the slow stuff.
Only piece of advice I have, is if you catch a fish, you want to work that area real hard, they've been grouped up lately and if you catch one, there should be more around. I'd work a Ned to follow up on those jerk bait fish or maybe a grub if you don't like to fish the Ned. I'd work it real slow, drag it and shake it, in 10-20 FOW. You can also get a few vertical fishing it if you see fish or shad on the sonar. Just pull it off the bottom an inch or so and gently shake it (the Ned).
Maybe pick up some 3/16 oz heads for the windy days, I fished that size Friday in the wind and caught fish on it.
If I'm telling you stuff you already know, my apologies.
Keep hammering at them, this time of year your next cast can get you a biggun.
