I've got a Top Tier as well but only 2 burners...I still mash in a cooler but have been considering moving to mashing in a pot.
One question for you....I get the gravity feed from the HLT to the mash tun (left I assume)...and I think I get the recirc pump which I assume is recircing the mash and sparge water.
How do you get from the Mash pot to the BK?
(p.s. I agree with you about lighting the burners)
