The comment about cave diving's risks being manageable was made by Clive Westlake.
I don't think new, tourist cave divers should learn on CCR with OC bailout for the reasons that Clare Gledhill stated in her reply on the OTHER thread. In a nutshell, you need to know what you can/can't achieve on OC before you are forced to rely on it when your RB goes wrong. If you have an aversion to cave diving on OC, the only way I can see that learning to cave dive on CCR is acceptable is if you have CCR bailout.
I'll see you in France then

I think a cast of thousands are going to be helping Rick, which should keep him happy !
p.s He was only still working on his prototype nano-rebreather at the time of the Truffe push. We had to hear about it all the way down to the Lot.........
