| I have this same problem actually but reversed.
I have a set of twin 12ss (alu 80s) and dive with them ALL the time.
What seem to be best for me is that I will make a set specially for single steel 15 liter tanks that I will buy. And will keep the other twin 12s.
twin 12s are good for about any situation and can have stages added when needed.
I bet I have been no help to your question, but this is my plan. |
