marty, like perry said 2 deeps for you, you should be good to go. i use 2 deeps, and then in the spring/summer, i stack the medium honey supers as they are needed, and leave them on until i harvest. i only harvest once a season. with the exception of comb honey frames, those come out as soon as they are capped. also, have extra supers on hand, it doesn't hurt. so perry recommended 3, have 5 on hand.
if you think your bees need more going into winter, leave a super on for them. hope this helps!
