Just received my Woo3 setup yesterday, and getting ready to try it out on 4 slabs of baby backs tomorrow. We got everything imaginable for a Large BGE; Woo3, extender, spider, 16" drip pan, 13" drip pan, 13" baking stone, oblong baking stone, 16" wok. We passed on the half moon stone options as I just don't see how we might use them.
This stuff is built solid; nothing rickety or shaky about it. Woodoggies done good when he dreamed this one up!
