Re: The Trimetal Choice...
34-36" pipes aren't excessively large. My pipes are all in that exact height range and I love em.
As far as the hookahs your looking at.. the Al Gia is nice, hookahstore.com also sells the same thing called a double trimetal, though I'm not sure as to what the prices are. (I'd check for you, but I'm in the last 2 minutes of class so I'm trying to hammer out this post before I go home, lol)
I personally like the heart of the lion trimetal and almost bought it a couple months ago, however I'd look into the KM Americana which is what I snagged... it looks much nicer than the pipes you're looking at, IMO.
I don't own anything cos you guys bought everything!
