I would vote for a Mya wide hose, a girlfriend of mine has one on her 19in. I used the ping pong ball diffuser method and it worked pretty well didn't notice a difference as far as smoke quality but its keeps from annoying my GF and cat lol.
Now for a recommendation you should get a tall bowl to compensate for the short hookah. Something like this http://www.southsmoke.com/pd_tall.cfm
or even the tangiers equivalent it'll even make it look bigger.
