We divers are passionate about our diving and almost to a fault. We tend to like what we like and abhor most everything else. We divide ourselves into cults without even realizing it. Shortly upon reading the threads and posts here on ScubaBoard, you soon learn that a Back Plate and Wing is the ONLY BCD to consider, that PDCs will rot your brain and that if you dive with split fins, you will surely die. For the record, I don't believe any of those things but you would think that these are immutable truths by the sheer volume of postings to that effect. For the record #2, it's way OK if you do believe any or all of those things.
