Oh no not the 'I am perfict and never make a mistake aproach to diving
'
Sorry, I am not perfict and do make mistakes.

This is where your ingrained knowledge of deco (or the stuff written in your wet notes!) pays dividends. |
I dont dive wreck dives on rule of thirds and neither do any of the other divers in my group. Bottom mix is generaly used up on the bottom. Redundancy is usualy carried in additional deco gas and or travel gas and drop tanks.
A rule of thirds dive to 70m would limit me to 15-20mins on the bottom on a £200 dive. Blow that for a game of tennis.
Rule of thirds is overhead environment stuff.

Deco or stage bottles are right in front of you and easily adjusted or disentangled, unlike a pony on the side of your twins, which is not. |
Like I said if you are worried about it side sling it with the other stage bottles. I have never had a problem with it so i prefer to have it out of the way where it can not be confused with a stage.

I quite agree but our individual choice of how to avoid it are diferent. I chose a system that is independent and totaly in MY control, and you chose a system which places trust in your buddy.
Your faith in human nature is far greater than my own. I have seen people do things way out of charictor in high stress situations and I have seen people turn into jibbering wrecks or freze when it hits the fan. You can never tell what a person would actualy do untill that person is subjected to the realiaty of the event.
If my buddy on the day it hits the fan turns out to be profesionisum its self I will be plesently surprised. If he /she turns out to be a jibbering wreck I will be alive to tell the tail.
