Newbierock, a standard conepiece is pretty small but you can actually pack a fair bit into it if you try, also that is far from the only size we have and you get Aussie conepieces in sizes not much smaller than American bowls, regardless of the size of a cone it is expected that it will be finished in one pull. It always amuses me that the rest of the world try and shit on the size of our cones when they don't realise it is very common for Aussies to pull a bong that is half the size or more of an American 'bowl' in one hit when you guys seem to take a fuck load more than two hits to finish your 'bowl'.
Shit a few years ago a friend of mine had a nice glass on glass American bong and we managed to pull the screen out and so long as we used a chunky mix we could punch those things like an Aussie bong.
To me personally, I LOVE smoking bongs, one could say I am addicted to it, and as such I enjoy smoking a lot of them. But really it is not neccessary to smoke shitloads of tiny cones like a lot of the rest of the world seem to assume, and this isn't even the norm among many smokers.
We just feel it is cleaner and you get a nicer hit if everyone gets their own cone than all hitting the same stale bowl. I am not down on anyones different ways of smoking and so long as you are getting yourself stoned then go for it, but I wholeheartedly believe the way we do it down here is the best and most efficient way to smoke bud.
