Going small

but to be sure profile and size can make it or break it

Got to add lure action to the mix.

I haven't seen much difference as regards the number of fish I catcht regardless water temperature and lures cast. Fish adjust to water temperature as is their nature. Fish attack lures that have the right action, retrieved the right way, in the right areas of a lake. Lures that catch fish in early spring, catch fish mid summer. As usual, larger lures may exclude smaller fish biting whereas small to medium size lures catch the most fish of all sizes.

When it comes to lure speed, lures that do well using a slow retrieve may do better than faster-retrieve lures types such as a Beetle Spin with curl tail grub. For that reason I like spike tail and Crappie Magnet grubs for their universal appeal in all water temperaturs.

Jig head weight is also important depending on depth fish: lighter in water fished within a few feet of the surface; a bit heavier jig in water 5' or deeper.
