Same here - no pattern except scattered along raised flats 40 yds from shore; average depth 5.9 - 6.5' not far from 7'. Beetle Spin/ curl tail grub has caught sunfish, crappies and yellow perch. Curl tails by themselves have caught those and a few small bass. Covered a lot of water with a lot of casts around the boat and sometimes caught three fish in one spot. Caught 15 fish on a sunny windy day (wind averaged 15 mph or faster - good thing for 10 lb anchors!)
When it comes to larger fish, you get what you get unless you hit a school of decent fish by shear luck which doesn't happen very often. But one way to insure larger fish is to stay with larger lures though fewer fish overall.
