Like crony says.
There are some heritage breed differences.
There are some suppliers that deal with certain groups of farms to buy certain age,fed,maintained hogs,and cut to their standards.
There are certain smaller cutters,mostly now bought up by the super producers,that have specs that may work for comps,etc.
As he says,follow the money.
You need to have a real need,to spend the money,for the small differences.
Now a couple grand,for 1/1000 of a point,it looks feasible.
