hi buckeye
there is a downside to what you are saying and pretty much any pot will work best when very little LN2 is left but what also happens is when the bottom gets exposed to air you start forming a layer of ice with reduces the efficiency of pots which this kinds of thing so i agree about keeping low levels of Ln2 but disagree about doing this for hours

Well that is ture, after a long bench session things do get rather frozen and even the Gigabyte board starts to degrade but at least it doesn't show any cold bugging.

If you watch this video and skip to about the middle of it you can see after a few hours what it looked like. You can see the amount of LN2 I was using and watch it boil down. I think it was 6-8 hours there at the end and I just filled it up for effect for the video, it was very frozen at that time. But the idea there was when running the pot with it full like that temps were warmer than splashes.

I like that gold pot you have and it looks to be very massive and I would say works very well for max temps.

One thing we noticed in testing was that huge surface area and a large number of sharp edges really transfers the heat well. I believe Chew had one of Vinces early proto types of Venom and tapped the holes inside plus a few other things to create more sharp edges and was able to get a bit more performance out of Venom.

I tried to show in the vid how the bottom of the Phantom circulates LN2 twards the center instead of having a pool of boiling LN2.

Its really hard to say tho at max LN2 temps with out a lot of testing equipment what really works the best. I suspect that a lot of these pot perform very close and really depends on personall preferance and pouring style.
