A little help, on ice fishing... please

[OhioVike]

I have owned a place on Lake Vermilion(WE) since 2011 and have absolutely enjoyed every visit and season on the lake.  Our knowledge of the lake and fishing patterns have grown tremendously.  However, this experience has not translated success onto the ice.  We catch some fish, but feel like we should be doing better.  Typically we use small gear 1/16th or 32nd jigs with minnows, Spoons with just a minnow head or when we go after panfish we'll use wax worms.  We fish all the same spots and don't catch nearly as big or many fish.  When we do catch most of our fish, it's typically on mud flats and we drill a lot of holes.  Any suggestions would be greatly appreciated.
