I need alot more evidence of that fact that your opinion

My "evidence" is that I have done the dives and know what works, and have discussed this stuff with those who have been doing it from the beginning. Other than that I have no interest in proving anything or arguing about it, but if you take the class that started this thread I'm sure the instructors will be willing to go over it in detail.

Thanks, but I think I'll just muddle along in my apparent ignorance along with the majority of the rest of the world.

Yes, but with mix you can see and remember the murk so much better

Or realize that it's not all just murk

Mix helps you see the murk better [/]

Except that I have been to the bottom of the more shallow lakes (60-80'), and it really is just murk. Silt, rocks, and the occasional boulder to break up the monotony. Boulders piles are Montana's version of a reef system. No fish to speak of, but at least we have some bottom relief.

Now, river diving is another thing altogether. The blue-ribbon trout streams are *awesome* current dives. Shallow, clear, and you feel like you're in a pod racer from Star Wars. Plus, it's alot easier to 'sneak' up on a fish when you're doing 3-4 knots.

the LEVEL of control necessary for a He-based mix is higher than that for an N2-based mix, correct?

Huh! Where in the world did you get this from? Somebody who knows someone who is a He-based mix diver? If you can walk and chew gum then you have the necessary LEVEL of control for a He-based mix. FACT (for the guy who wants everything backed up by Fact).

Is there not a difference in the level of skill that is a "safe minimum" for the two mixes?

Is there a difference in the level of skill that one needs to breath clean fresh mountain air vs. polluted city air, or fresh rose scented air vs. a smelly fart? I don't think so. Level of skill has nothing to do with what gas you put in a tank. The gas that goes in a tank should always be the proper gas for the dive, what ever the dive may be. FACT (for the guy who wants everything backed up by Fact).

Too funny thar Mate!. Are you a sock puppet, or is that a pigeon on your shoulder?

...pay no attention to the sockpuppets...

If you use helium in your mix then you had better be able to do a slow controlled ascent and make all necessary stops.

 

[The Pirate]

You better be able to do a slow controlled ascent and do all necessary stops no matter what gas you are diving. The rate of ascent from depth should be no different with trimix, nitrox or regular air. If you can't control your ascent, you shouldn't be diving.
