Ok guys thanks very much for your help and advice on my question I appreciate your opinions. Today I talked to my Instructor who is a technical diver and 6 other techy divers who have all been on british expeditions at some point or another. They all regularly dive over 80 metres and are extremely experienced trimix divers also, so there advice was not taken lightly. Apparently diverite just isnt up to the job, according to these guys, and other independant techies I have spoken to feel the same way. I will be going with Custom divers kit which happen to be a British made brand, so you people in the USA might not have heard of them.
