I have to put in another vote for comfobite
Aqualung Comfo-Bite Mouthpiece from LeisurePro.com. I was dissappointed with the mouthpiece that came with the copis...it was so thin that it left hardly any room between the teeth for my breathe to pass. Having owned an AP rig that came stock with a thick mouth piece that forced you to keep more space for breathing I instinctively was leery that the ISC version would effect the WOB. In any case I like that I can keep the comfobite in my mouth without having to bite down on it. virtually no jaw fatige...it has a retainer looking thingy that goes against the roof of the mouth and is made of soft material.
