The only thing that I'd sound a not of caution over is the bit in bold above.
If you are hog looping, DO NOT clip the stage off anywhere other than left hip/left shoulder* or you will risk trapping the long hose, which may cause irreparable damage to your buddy...
Equally if you use an Ali stage, it should only ever be about +/-1.5kg off neutral....
*yes, yes, I know you can go right hip/right shoulder and get away with it if you know what you're Doing It Chasey...

Don't trust people on the internet with your life, your credit card details or your naked selfies! This advice may contain, or indeed be written by someone who is (clinically), nuts.
what about brexit, scottish independence, youth of today, corbyn, international terrorism? oh and where the hell have the cheeky girls gone?

what you really need of course is to balance your stages on each side taking into account the molecular weight of the gas and the buoyancy characteristics of the cylinder (material, wall thickness, weight of valve, etc), before we even get into top of shoulder vs over the shoulder vs back mounted counterlungs, but as usual we are now getting waaay off piste for 'how do I stop my sinky feet?'
I still haven't sussed it and so far I've ended up with using steels for trimix and ally for nitrox like mark does but it's still not perfect. Fair play to the gueeeeys who can manage one arm full of stages that must be negative as a barrel of bricks.
well, following some good advice on here, I went back and got my buoyancy and trim re-assessed yesterday - totally nailed it: Graded "Ninja" Black!
(Not quite GUE standards but in BSAC world, that's holding stops to + or - 30 cm for 2 mins each at numerous depths: including 30secs at 1m which is interesting... )
Quite chuffed - especially as the assessment dive was only my 20th OW dive
Come down to Chepstow on Saturday then - I think there's still one place left!
To match the TDF vibe : I bought a rebreather, well my fourth.
One of the first things I did was get it in the pool in all the kit, yes gloves and hood, and in the shallow end (so I can reach my pile of weights on the bottom) I trimmed it for neutral buoyancy with weights in pockets et al.
Then I carefully put everything in the right pouches except for 2 x 2Kgs which I held in my hands.
Then I just hung in deeper mid water and moved my hands from my waist to sticking out in front of me until I found the 'trim' spot.
Trim is balanced so where you put yourself there you stay.
I noted the exact position of my hands and worked out the 'moment' it applied (weight * distance from my waist as roughly the balance point)
Then I worked out how much weight that was as some convenient point to actually attach it. Remember I am just moving weight now not adding or subtracting.
I fixed it there and went back in the pool. Perfect.
Camera nose down in a hole, upright or classical 'flat' deco position. It just works.
I actually look competent which is a mean con trick as I'm not.
Physics is fun

Helium, because I'm worth it.
Waterboarding at Guantanamo Bay sounded like a radical holiday opportunity until I looked it up.
