Nakhla is a drier shisha for sure. Like Sammn said about the heat management. It's easy to smoke but also easy to mess up if you aren't careful. If it starts getting harsh take off the coals and exhale through the hose a few times. This does 2 things. It clears the harsh smoke in the vase and cools the shisha down quickly. Then put your coal or coals back on along the edge and try again. I find I get my best sessions with Nakhla in an Egyptian clay bowl by using 1/4 of an Exotica stick and a windcover.
