Sorry if that wasn't clear, here's what I do using a single kettle:
Heat strike in kettle, overheat a bit actually. Add to MLT cooler, cover, allow to pre-heat. Stir down to strike temps (just above actually) then dough-in.
Mash as usual, heat sparge water in kettle (same single kettle). When mash complete, either drain first runnings, or mash-out then drain runnings into a bucket or extra pot. Add first sparge addition to tun, vorlauf, and if kettle is empty (single batch sparge), run wort into kettle. If kettle still has sparge water, empty runnings into bucket/extra pot, do second sparge addition, run into kettle and add initial runnings from bucket into kettle.
Boil, chill, pitch, etc.
I have another 8g. pot slated to be my HLT but I just haven't gotten around to fitting an element (electric) into it yet.
