I'm thinking of buying this bong for a vapebong setup using an herbalaire 2.2: 07" CLEAR GLASS WATER BONG - 05 [1062] $14.99 (can't get the link to work but its off of Bong Outlet) - 7" HEIGHT How can I tell if this bong is 14mm or 18mm? Does any one have this one? I need to find a cheap bong that will work with one of these adapters to hook it up: Vapor Brothers Ground Glass H2O Adapter - 14mm @ VaporWarehouse.com
