Sirloin tip is cheap for a reason! If you gotta go cheap, pot roast chuck, or rump. Dry roast, eye of round can be ok if larded. It won't be real tender, but ok Google recipes, use the one where you put in a 500 degree oven cook it a short time and turn it of. capt david
I agree with capt.
Having said that, buy one and try some methods prior to Christmas. I would actually try to smoke it at relatively high temp until it hits 125, then let it rest. Not sure it will meet expectations, but it might.....
