I live on a lake; my smoker is +-200 feet from the shore. It's too large to move around, so in answer to your first question; I dont move it. Regardless of type of wind and/or direction, it stays the same.
For the second question, I use fairly large VERY dry (and warmed usually) splits. It's RARE that I use an unsplt limb section.
