Nitrox - Trimix

[dofundive]

Diving with the big steel tanks and dragging along 2 deco bottles, I guess I wouldn't consider the argon bottle to be much more of a problem. You are correct though, in that it is another set of things to consider (cost of buying and maintaining argon fills, argon reg, argon bottle mounts). IMO the extra cost and  trouble of the argon rig outweigh NOT using the tri-mix.

Not every trimix dive has to have two deco bottles. I do not swim my deco bottles when cave diving and was thinking about a tank mounted AL-14, which is kind of a pain.

The drag is not a major issue, (None at all for the 6 cuft) but as long as we are considering all the trade-offs...
