Michigan stinger spoons are popular.Get an assortment of colors.I usually will start with green,white or purple with a copper back.As for adding the weight to cranks any 2oz sinker will work.Attach to a release like the ones you have on your inline boards or even a rubber band.Put out crank 50 ft then put on 2 oz sinker then another 40-100 ft of line then attach to board.That should get you around 8ft deeper than the total amount of line out Good luck
