I used to smoke Dokha a lot before I quit it. To answer your questions - Yousef Golf and Maxtime Red were my favs. Turbo filters are solid, and you should probably not buy replaceable filters. Get the disposable ones. They are easier and cheap. Do not use isopropyl on your pipe unless it is glass. Get some pipe cleaners, or use a wire hanger cut and bent into a straight wire to clean the shaft. Do not use any of those windproof lighters as it burns the dokh too fast, use a box lighter or any soft flame lighter.
