Re: hookah hookah evollution tea-sha??
It's worth picking up some 50g samples from Shishabuzz as they carry loads of their flavours to try it. The only way to find out if you'll like it is to try it really, so it's worth dropping a little amount of money on it.
What I would say is that you should buy flavours which you have smoked in other tobacco based brands first so you know it's a flavour you enjoy smoking. If they then agree with you, then you can try some of the other flavours.
