Re: Some help for heat management for Nahkla,
Nakhla needs stable heat and a bit more than normal tobacco (an normally more than QL's can offer steadily). If you must use QL's get a windcover - you'll have to be Johnny-on-the-spot with the management but it will work.
As to the bowl pack, I overpack Nakhla (just over the rim of the bowl) and tamp it down flat. Make sure to move the coals OFTEN and at the first hint of burnt - REMOVE the windcover and/or a coal. It's doable, but make take practice
