Re: Will the KM be an upgrade?
^---keep in mind two things about the above hookah.
1. it will not have autoseal (one of the reasons it will have a better draw)
2. I don't know if the four hose models have a purge(i know the 3 hosers do), but you can just as easily purge thru the opposing hoses...and if u purge thru all three it will actually be faster than having a purge.
EDIT: I guess in the picture it does look like it has a purge on it, but it will still probably be more beneficial to purge thru the hoseports.
