Oh, I know all that, but in all my years I have never had a bad backstrap, even slicing it off the deer and throwing it on the grill. Other muscles, yea, some can be tuff if not aged, but never the backstrap, tenderloins or heart. I normally decide during the processing on how I want to cook it, so can cut into steaks and not worry about it. Vacuum sealing it takes care of the freezer burn issue, but even before then I would wrap with saran wrap getting as much air out as possible, then freezer paper. Had venison last 5 years (am always losing a piece in the freezer) doing it like that with no freezer burn.
