I love hevi but it is expensive. 6 years ago i bought two case cheap from Waterfowler.com. I'm still firing the stuff from back then. I love #6's for ducks. I try to use it most of the time when i hunt geese. It really helps you and i fire #2's for geese.

With ducks I'll use it when it's a slow day or when i might get into a new species of duck for my wall. If I'm targeting a new species I always pull it out. When I hunt honey holes where shooting is close i usually load steel. I like to use HS on divers in the layout at times also.
