A lure initially designed for ice fishing has become a productive wintertime bass catcher on unfrozen waters.

Been using the Rap ice jigs about 40 years  in our deep rock structure lakes.

Suggest flattening out the nose & tail hook barbs and going up 1 size treble hook. Use care removing the treble hook as the hanger can break.

Bass tend to get the lure sideways in thier mouth, that is way to flatten the bards.

Practice working the ice jigs with the rod tip so it swims in a circle where you can see it. This takes easy rod tip work and the action you want.

Caught a lot of fish with it last month.  Mostly around deep brush (25-32 FOW).  Fished surprisingly well around wood.  Like a big spoon, it is heavy enough to be its own plug knocker. It has crazy gliding action.  Hooked probably as many crappie as bass.  38-41 ° surface temps; 7/8 oz Jig Rap; 50# braid; all vertical.
