We went to pork meat with fat on it because it gives a little pork flavor to the meat, and we like that. In a few years we may not, and will do it another way...such is the way of the home butcher...whatever suits his/her fancy.
I've been told by butchers that pork fat/meat turns rancid faster in the freezer than beef, but I've never noticed any change in ours after more than a year.
