for bass what depth do you like and how far down do you put your bait??
Bass can be a lazy fish in the winter, especially the LM's.
As for SM's, rock piles, or rocky points are very productive. I usually look for 10-15' FOW around these types of areas. But I always try to vary depths, some 3-5', some 5-8', some 10+. I always do good 1-3' off bottom.
I always try to set up over a weed bed for LM's. 3' of cabbage in 10' of water is GREAT. You can put the bait right over the weeds, and be sure one will be by soon.
One of the biggest tips is do your research during the summer months. Find the keys areas the fish will be.
