Water pipe? What are these pipes that you speak of? Plumbing? Seriously, its all personal preference. Check my Youtube! channel, for some idea how different sizes and styles work with the Box. I use most of my pieces with the MFLB and the WPA, or WPW (some are homemade). EDIT: Also, if you plan on buying all these goodies, I would buy an exotic... so you get the turbo-charged batteries.
