The request is a very reasonable one... I would suggest that those people who do have OC trimix should plan to get a CCR trimix card.M
Indeed reasonable, just have a look out of the position of the responsible dive centre or dive master letting you dive without a specific cert...all ok when nothing happens, but if....
And let's be honest that there is a big task loading on a bail out situation on ccr, especially when deeper then -60m it needs a cool head, not to speak about difference between training and the real bail out...I had a student with a full flood at -70m during an adv. tmx ccr course, he now understood why he was trained with 'no mercy' and my hart beat was faster then during my long time ago experiences at car racing

(The membrane of his adv was split in two...)
So a cert is one thing, and keeping the skills is staying alive after 100 hours of diving a unit with not one problem.
