RE: backstraps vs. tenderloin
Like Chef said ... get the tenderloins out as soon as you can because they will dry out real quick. I get them out and put them into the refrigerator (or cooler) and either eat them that night or the next morning.
I also use very little seasoning when I cook them... just a touch of seasoned salt and pepper. Usually I lightly fry them with a few eggs in the same skillet.
