Tom: Re safety vent hole: The Powerball Co2 valve has had the safety hole for many years, but Loctite could sometimes block it. Their new pi approved Co2 valve has an extended inner thread and two flats down either side of the thread which would make a loose valve VERY obvious if it began to come unscrewed while there was Co2 in the cylinder.
Dark Stranger, Ditto your experience. I have also managed to loosen my air bottle from my reg whilst there was air in the tank...and i'm not the strongest baller out there! Be careful out there peeps!
