i wouldnt really want to smoke something that puts me on the same level as sucking a dick, i think the regular bong design is perfect, but like he said whatever floats your boat. and as for hitting hard all bongs will hit the same so long as there arent any leaks anywhere or paper towels shoved inside them, in fact i think if there is a difference either way, the spiral would make that one hit not as hard, since the smoke has the added obstacle to be forced through a spiral, yes it would be cool to see at first, but it is something that after you used it for about a month youll probably just forget about.
