I've used both. Actually come to think of it, I used the pre-mixed from alphatherm and buttered the inside edge of the bricks for the dome and then used homebrew to fill in the gaps in the back side because those gaps are wider and the pre-mix is pretty expensive. Worked OK for me. Just make sure you get the air dried pre-mix not the heat set kind. If memory serves me the air dried stuff is not water soluable when dry. Not that you'd be getting any water in the oven when done, but more peace of mind.
