Right. I am pinching twin 12's full of 18/40 cos a chum of mine is buying a twinset and he won't use it. So...
1. Decant 80 bar off the twinset into another identical empty set.
2. Add 20 bar of O2 to the 150 bar left to make 170bar of 27/35
3. Top off with air to 230 bar. I reckon that's 25/26
4. Take the other twinset with 80 bar of 18/40
5. Add 34 bar of O2 to get 114 bar of 43/27
6. Top off with air to 230 bar. I reckon that's 32/14
Sounds about right. I know what you're doing but 25/25 is much more useful for everything really. If you get blown out from one thing and have to hold it over for another dive - 25/25 covers anything in the 30ish down to 45m very nicely IMO
I guessed - they're actually 28/25 and 32/15 - you might be better off cutting some of your own for 25/25 with something like Decoplanner. I'm sure Ian will run through all the options mate
Are you sure you are approaching this with the correct mental attitude Woz? Apparently OC Trimix is for the financially profligate. Your scrimping and scrounging gas from left overs is a bit like watching a mate construct a rolly up from the dog ends at the end of a party.
Best thing is to blow off both sets whilst singing the "Chasey sh*gs Herons" song then take it to your LDS (well actually the most expensive dive shop you can find) then demand a "within 0.1 %" tolerance of your favourite gas.
You'll be giving us a bad name with this frugal approach to Trimix diving.... next thing you'll be using 32% and 80% for deco and filling your suit with a whip from your deco bottle.......shakes head . Mal

The idea is to plan and execute the dive on tables. Perfectly fine by me. Would be nice to sort out the gas first, though. Would be such a shame to drain and throw away a twinset full of 18/40
