Lamb is one of my favorites! I have never smoked one, and don't realy think that I would, I am heavy handed with the smoke and don't think that the lamb really needs it. If I ever did try to smoke any I would have to do it when I only had like one chunk of wood on hand.
At any rate what I failed to mention is that you can search the linked site for a host of other stuff like "Ribs", "pork bibs", "Beef ribs", or "Beef cuts" or other type food questions and then scroll down to the knowledge base for some pretty informitive stuff. It may be basic to some, but for a simpleton like me it was almost over my head.
I am not pimping the site, just passing along what I found.
