Thanks for all the info guys, the old noggin is starting to vent steam to allow the CCR pressure point brain cells vent off! the MCCR and ECCR is something I still am not 100% done on, because some divers have used both, as said, its then down to picking which unit suits me and go with the flow. Ill keep you posted on what system I choose, if its a good one Ill post soon, if I made a bad choice, keep the eye on the obituaries in the Daily Spew, for the respect of my mates Ill get cremated, lugging a box with me in it just wouldnt be right
