Hi Guys,
Thanks for the feedback.
Wiz,
Want the button on the front of the lung as the side mount will cause hose routing issues, and on the front it will be out of the way (starting to get a little cluttered in the centre with dry suit etc)

Thanks for the link, but I'll just bludge on of chriso (free and pre cut)
Stefan,
yep that's what I was talking about
Chriso,
Yes please I'll grab the gasket. No you will not be allowed to go near my counterlung with any pointy/sharp objects

......ever. And no we will not be using my Dremel to do the incision!!!! When are you coming to Sydney then?
