Re: No taste and lack of smoke
Make sure you're letting a good amount of heat get to the shisha. Getting CH's will probably help too, as I have never heard of "Taru" coals. And the vortex will most definitely help as far as flavor and the lengh of your session, and as long as you pack it right, your smoke, along with a tight foil seal, 2-3 coals and a clean pipe, should be plentiful. Also check to make sure you don't have a subtle air leak which might obstruct smoking.
