Thanks for the love guys, and all the info. For those that asked, it didn't have any gameyness that I could detect, it ended up tasting somewhere between pulled pork (the smoke) and shawarma (garlic and the lamb itself.) Except unlike most shawarma I've had this was actually very moist. I've always seen lamb taken only to medium rare, but I figured with such a big hunk of meat it could go all the way to pulled pretty easy too.
WSM just arrived yesterday, so it looks like I'm going to take her for a spin this weekend. I'll go stock for the first few cooks to break it in, but I've already got the list of mods I want to do from this forum lined up. Thanks again!
