Gangly,
Here's the Norman's I was using.{ Chrome Black Back}.most were caught on the 2 1/2 inch model I found in a tree years ago..dives from 8 - 10 foot.
The bigger model I caught one nice one yesterday dives from 10 -14 foot..it's body is 3 inches long.
These lures have a great wobble..you cast long..crank hard when touching the bottom use slow irratic retrieve..the wet sock feel is your fish. Those green ones are hot..I boated an 8.2 a couple years ago on that one .Bomber A firetiger
