just that I think there is a bad trend for ccr divers to start doing deeper mix dives without proper instruction (on bail out gas planning and optimisation)
I am sure agree with you, Mike, and it is not my purpose to tell diver go, it's simple you just have to get V planner and go dive.
My curiosity is because I saw almost 10 divers with different way (good and bad) to solve deco planification with CCR and by this thread I hope see trend or strong line to solve it better.
It permit also to tell on a forum what are good and what are non sense, if many use trimix, heliair, triox, heliox or what.
The goal is not to supply or demand a course but at this time who are doing what.
I hope this can help all beginners to make better his own organisation and show many good solutions.
