My current wing (Mares) is only "lift rated" up to twin 10s -although it copes with an extra ali 3 ltr no problem.
I will be doing trimix later/early next year and so want to upgrade to twin 12s + need to cope with stage cylinders.
I have seen, on YD, links to web sites with info on DIY wings + maybe Dominic has some info on his web site. I would be most grateful (not that grateful you pervert
) if someone would pls post details again.
