Why the jumbo vase? Ok, it's nicely shaped but the thing is freakin huge, and worst of all, the neck doesn't even come close to lining up with any of the KM's I've seen on it yet. I like the neck of my vase and the heart of my hookah to be flush or close as possible, to me the 1/4 to 1/2 inch that the jumbo vase flares out around the heart just makes the hookah look unfinished and cobbled together, which is a horrible prospect for one of the most expensive vases!
So why do you jumbo owners/enthusiasts like it so much?
Note: The above is based purely on my own taste and sense of hookah aesthetic, I'm not trying to poo on anyone's style or hookah, just sayin'.
