Thanks for the compliment? With all due respect to you JC, nowhere did I say sorb was "better" in some ultimate, overarching sense than EACs, that's not why I piped up. Things were being said which were not true and I pointed out that not everybody who goes beyond the mnf recommendations is a suicidal cheapskate who should be purged from CCR diving. The glaring omission of a granular scrubber option for the Optima means that for most of us, it's not feasible to use an Optima in most remote locations, where some of the best diving is. So, duration is obviously important to people who travel to dive and this was not being taken fully into account in the discussion. Instead we get people quoting mnf specs, making uniformed judgments about other's motivations and posting stuff that's not accurate.

And last time I checked, you don't have to be an Optima "OWNER" to post on any thread. Things would become very boring and cliquish around here if that were the case. There have been many uninvited comments on Prism threads and I don't recall anybody trying to chase them out with anything more than logic.

I've said many times that the Optima is a good unit and that EACs have some very good features and I would like to have more CCR divers available to dive with in the beautiful remote parts of the world, not less. Maybe the Optima designers will finally get the granular scrubber out if more people complain about this blatant limitation, that's my beef, simple as that... -Andy
