Congrats. As far as the heat deflector, I am not sure how you can get any better than the KJ one. That air gap is perfect. Have not used a split deflector. Thinking of a BigJoe this year, that price you got was awesome. What a deal. So much fun to cook on, in any weather, at any temp. For me it's a true northwest grill, doesn't matter what the elements are, I can roll however I want unaffected. Enjoy.
