Re: Confusion with Hookah Taste
Are you a cigarette smoker? That can destroy your senses of flavor and scent. A lot of hookah flavors are very light and if your senses are dulled it will entirely disappear.
I don't know Deja Vu. I am not entirely sure about it's quality but from what you said it seems to suffer from the same issues with double apple that a lot of modern style tobaccos do with double apple.
Al-waha is not exactly touted for it's striking flavors and high quality.
I suggest changing out the tobacco you use. The bowl should be fine. You will get the same flavor from a funnel as you do from an Egyptian.
