I know that much, Andy, and that's partly why I use a manifold myself. But an independant system is simple and has merits. It can be used safely if used PROPERLY. That's what I'm saying. If you blow a tank neck oring or a burst disk you then HAVE TO isolate the regs AND switch regs. On independants you would only HAVE TO switch regs. As long as you managed your regulator switches and your gas in each tank properly you will not have a problem with independants any more than you will have a problem with a manifold. I still prefer a manifold but do dive independants occasionally.
