ya their done.
The gist of the debate over good vrs. bad lots, had largely to do with ambient moisture in a given region or season of year, and the individuals shot too shot bore condition ritual. The stuff would work great in Nevada in the summer, yet awfull in Florida at the same tyme. Guy's would have trouble in the winter/rainy season in Texas, and it'd work great in the dry air winters of the Great Lakes. (get it?)
Those debates where/are about 3-4 years old now. I remember some extensive logging of lot#'s on a few sights at that time, perhaps a reveiw of "archived" info from 2yrs back or better will yeild a better idea of what was happening.
If you can get Elephant for 8-9$ a pound or so, don't hesitate to buy. The stuff will shoot if you do your part. Much over that is inflated prices,,mites just well buy fresh stuff
