I started packing Nakhla tight in my phunnel about 2 weeks ago and have had famous results. While I use a similar method packing tangiers, fork it in past the rim making sure to fill in gaps then pressing it down, I pack it a bit looser with the Nak, essentially not filling up nearly as high before compressing, more like to JUST past the rim. I also use slightly smaller holes than when I smoke Tangiers.
Only way I'll smoke my Nak from now on, last night I opened up the kilo of DA I bought and was sooo damn happy with the results
Funny that the loose packing method is being challenged since that's how I learned to smoke. Personally I'm getting better results with tighter packing.
