Not yet. Have you tried a great marinated pork tenderloin? Much more flavor than a loin. Kosmos Q pork soak was made for pork tenderloin. Try it it's fantastic and it ain't me alone that thinks like this.
Around here, pork sirloin tip (a better cut than "loin" is actually cheaper by at least $.50 a lb. I buy 'em @ Costco @ $1.99. Rub 'em with garlic EVOO, season 'em with your favorite and smoke 'em to an IT of 150*. YUMMO!
