The best pulled pork is from a smoked Boston Butt or pork picnic roast. I suggest a recipe such as here: http://barbequelovers.com/recipes/pork-recipes/secrets-fo...
I also love a good cider vinegar mop throughout the process, which you can find here: http://www.meatwave.com/blog/barbecue-recipe-big-bob-gibs...
There are a ton of great pork butt and shoulder recipes out there. If you have access to a smoker, don't do it in the crock pot. A smoked pork butt is totally worth the effort.
ETA: My personal opinion is that Lloyd's is GROSS. But I don't like my pulled pork "wet" (with sauce mixed in). It like it smoked, dry, and flavored by the mop sauce. YUM!
