Re: I would need your advice on this hookah...
That's an old KM butterfly stem on a genie vase. Hookah Company has that stem and genie vases also but they may not have that exact one. I know they have blue ones though.
Personally I prefer the new KM butterfly that can be seen under Khalil Mamoon Premiums on Hookah John's site, mostly because it's one of the wider gauged KMs.
