Like mathauck0814 pointed out, the problems with RMS is commonly known, it is no secret just go on CCR Xplorers or Rebreatherworld.
tstormdiver - Not to contradict your instructor as to what you were taught, but a proper pre-breathe is done while in your rig. I have seen several problems that have come about and would have been picked up if the diver did their pre-breathe while in their rig opposed to standing next to it! Not doing this way is a bad habit/procedure to use. I understand about drysuit, water temp, over heating, I am a NE diver. Do a quality pre-breathe (while in rig) and knock time down to 5 min.
