If the actual tank tot he valve goes, it just leaks a very small stream of bubbles, and you or your buddy should see it and get it looked at.
A good option that I saw was John Duncan, who had a single tank with a Y-valve, well, more of an H-valve, and screw the 2 1st stages in. Worked well changing between twins and singles, and has more redundancy than 2 2nd stages on 1 1st does.
Why not just buy a pony and use it with the 15s? You could sidemount it, so you're not carrying the weight around too much, and if your diving prgresses, as well it might, you can use it as a stage. Easy. |
