Once again very lucid and informative.
I always read the interesting snippets regarding the use of dive tanks and filling PCPs on this site.
However the information is scattered all over this forum and difficult to absorb as it is not collated. Frequently there is an important safety issue discussed.
With your skills would you consider doing a newbie's guide to "compressed air tanks and PCPs for dummies"?
Many members shoot at clubs and exchange info there, but there are quite a few out in the sticks who are doing a lot of pioneering (Pioneer = the oke with all the assegaais in his back).
