Personally, I'll buy from wherever is cheapest and get training from whoever is best.
For me, that's a different unit, straight from the manufacturer and training direct from the manufacturer. An option not open to most people I understand.

Yes or no questions Paul.
Can I buy one of your units from Jim, get training from Jim and do this training in North Florida?
Can I buy one of your units from AddHelium get training from AddHelium and do this training in Key Largo?
Can I buy one of your units from Jim, get training from Jim...
I dive GF 35/85 normally.
Sometimes I do deco dives in caves that then requires hauling lots and lots of heavy bottles out through difficult, strenuous cave passage.
I pad the stops.

My best SAC ever was 8lpm, or 0.28cuft/min
My average is 15lpm or 0.5cuft/min
My worst recently was 32lpm or 1.13cuft/min.
But I don't know how to do the silly imperial measurements properly. Anybody care to fact check my figures?
Should also state that these first two are considered...
So is it actually a buddy or is it two divers same sump?
Personally on the same dive Id use 12L 45% (I can't do imperial cylinders) as I don't have a CCR, but I'd give myself a half hour difference between me and another diver.

Seems unnecessarily complicated.
Also, you're going to struggle to keep a drysuit whole against the roof.
But I accept that's a fair answer to all. What's the benefit though?

OK. The sump is 70ft deep, 330ft long, 12 inches high bedding plane. The route meanders side to side as the fine silt floor changes where it banks with every flood. This fine silt floor also causes zero vis (close your eyes kind of vis).
1. What size cylinders are you using?
2. How do you...
Respect yourself. Do what you want.
That way you get to do what you want and at least one person respects you.
But, you may want to ignore this post.

I've never used force fins so probably shouldn't chime in.
But I have tried tonnes and tonnes of fins. I carry them down caves, decide I don't want to carry them there again so leave them there, then I go begging local dive clubs for old fins.
A few months ago I was given a set of jet fins...
Speaking as someone who dives almost exclusively in low/zero vis, tight environments (gauge readers required zero vis) the only way to do these dives is solo.

At the moment I'm just ignoring the problem. It still charges and for 13 years I've never had a computer that exports files, so I'll live without it.
I keep meaning to have a proper play.

Hate to say it but you're wrong.
Cave Diving Group started training civilians to dive in 1947 using standard dress, 1948/49 using closed circuit scuba.
BSAC started teaching civilians to use SCUBA in 1953, a year before the LA program.
That's just the UK. I'm sure France probably did...
