holy 3 year thread!!!! :O
i'm a fan of both. i'm actually ading about 1/8 tsp to each bowl of nakhla now because i do have a sweet tooth. i like smoking in a phunnel bowl and it makes nakhla smoke perfect for me. it lasts about an hour longer, the taste comes out stronger, and the smoke is thicker.
but if you overdo it, the whole thing tastes like soap. some of you might say stuff like "adding glycerin to nakhla is an abomination reborn." these are the people that have never tried it.
