Disclaimer: This is an advanced thread, I do not advocate beginner-to-intermediate divers ditching their octo. In a thread about pony-bottles, the topic of whether or not to ditch your octo came up. Specifically, someone mentioned being unable to access your larger air supply, if you use a...

I almost exclusively dive back mounted doubles here in Norway, and when I went to Dahab last year I was able to rent doubles, but many places in the world that's going to be tricky.
