Hello Jarrod,

Thank you for your interesting message.

Really sorry if my comments are not really befitting my normally reserved
attitude, but when I read intolerant or untrue assertions, I don't want to
have a reserved attitude. let me explain you this in this following message.

Redundancy.
I am sure a lot of people have thought, certainly before me of the redundancy.
I am not the "inventor" of this concept, and even if I was, an idea is never
patentable ! In fact, I have developped the philosophy of full autonomy and
rebreather's redundancy in extrem (cave) diving. In fact , that means to dive
100% rebreathers, without any extra safety open circuit cylinders. And the RI
2000 was really the first rebreather system thought and conceived for that.
Nobody can contest this fact. You have another approach, and I perfectly
respect it. But, when I read that my philosophy is suicidal, kamikaze or
others insulting assertions, you are right, I have not a reserved attitude.
This intoleranr , integrist attitude is intolerable. I am exactely the opposit
of a suicide man and my concept was extremely safe.How one who never used this
kind of configuration can assert such a purpose ?!

If I have well understood, You plane to use double rebreathers in the future.
Congratulations. I should not be surprised to see one of this day the double
rebreather integrated in the DIR philosophy ! A great evolution, when I think
that two years ago, rebreather's redundancy was considered as a stupidity by
some members of the WKPP.

About the team approach, I am not opposit of this approach. But, don't forgett
that you have enormous potential with Leon sink, Wakulla and other systems. So
you can gather a lot of divers. In Europe and other countries, it is not
possible, so teams are much smaller. Just a little remark who would like to be
positive : Your team looks like a pyramid, with a lot of support divers and 3
or maybe 2 "top divers" (you and Irvine). It could be great to have 6 or more
top divers with turning top teams for explorations. A good idea, no ?

All my best

Olivier Isler

P.S. This coming Tuesday, I will be away for a couple of weeks, so, if you are
interested to have new discussions with me, we could take contact at the end
of October.
