These are a new bait for us.  They are similar to a RK 55.  Dive  9-14', body is 2.5", and is 1/2 oz. , will have a size #6 VMC short shank treble hooks ( I can replace with a #4 Mustad if requested ).  They have an aggressive wobble, and bounce off bottom structure like crazy.  I think they will be real good for casting.
