even ice diving there is no need. I've done it and had no problems with a proper undergarment.
Argon use

geraldp:
I use a 6 cu. ft. bottle and can easily do 2 deco dives (120 - 150 fsw) or an entire weekend of shallow NDL dives. My buddies, who are cavers, use the larger bottles for caving because their run times are longer.
With regard to pre-purging, I believe that it does make a difference if you really make an effort to get all the air out of the suit. I usually fill, stretch and dump 3 times before I get in the water. By the third time, I can feel the warmth.
To accommodate this, I carry an old Steel 46 with an OMS deco reg first stage and an LP hose with me on the boat. It is small enough to stow like a stage, and I don't need to touch my small bottle in order until I am ready to dive. In addition, I can transfill off of it.
I find argon particularly useful when diving helium based mixes. I cheated once and used my back gas to fill my suit on a training dive. I froze my butt off. The difference is less pronounced when I dive Nitrox. I use argon then, primarily because its easier to fill off the argon tanks in my garage than it is to go to my LDS and fill with air.

I dive a 6 cf argon rig here in Monterey and I swear, placebo or not... it's warmer.
Here it is:

OK now we're getting off the topic but how does the new webbing suck? That stuff is great! It's not too stiff and it's not too flimsy. Is it the H's that are bothering you?

No (not the H's...but they suck too )...way too soft...I like stiff webbing.CALI68:OK now we're getting off the topic but how does the new webbing suck? That stuff is great! It's not too stiff and it's not too flimsy. Is it the H's that are bothering you?
Heck...I I'm going to use the H webbing for crotch straps...an H G-string so to speak

The only scientific study (that I'm aware of) that's been done on the air vs argon topic found that there was no measurable difference between the 2.

As already mentioned, helium mixes do rob your heat & you would not want to use that as a suit gas.
