Re: Isfahan Tombak
In terms of actual design the base and mainstem of any well designed and built narghile should work fine with tombac. What differs is the sort of bowl and hose used. Getting the proper bowl and hose in the U.S. is basically impossible so if you want to smoke this sort of thing you need to improvise. What I recomend is that you use a funnel, vortex or a conventional bowl that is wide in diameter with very small holes. In terms of hoses you want something that is free flowing so go with something that a wide diameter.
