this is how I pack my Nak Mizo in a vortex:
Put tobacco in the bowl about half way up the spire. Then pack & smush it down pretty densely. Then add more tobacco so that it is just below the foil. When you add more tobacco the second time around try to keep the tobacco away from the holes in the spire. Then add a layer of foil or two, poke holes, and enjoy.
