Be carefull m8, sending up lift bags with deco regs is dangerous, ask any one who's done it a lot.
The neck of the bag can grab the reg and your hand and take you up with it its also very easy to get the reg tangled in the webbing straps or the lifting rope. Its also not as easy as it sounds to get all the gass in till the bags up a bit. As a result you tend to stuff the hand and the reg right in the neck and then your in trouble.
Personally I prefer dog dick inflater's as they can be used just over the lip of the bag with virtualy no loss of lifting gas. Also they have hardly any entanglement points.
Lift bags are dangerous. I know more people who have had rapid ascents from max depth attached to a lift bag than for any other reason.
For this reason I use a detachable dog dick type inflater and I have a spair inflater hose on my shallow deco / bailout mix.
If I should lose my shallow deco bailout gas its not a big problem as there is a drop tank on the boat. If i lose my deep bailout I am in trouble.
First line of attack is my suit inflation bottle of air. I use a 1.5ltr bottle to allow me to lift small stuff (up to 25kg) with suit inflation gas rather than use up deco or bailout gas.
If i were planning on lifting something big id take a task specific tank. Generaly i dont lift big stuff.
Id empty that first then go for the deco /bailout mix. I really don't need suit inflation gas once on the bottom but if i do, I plumb in my 80% and try not to fart.
