Damn Splave. You and your exploits made me snag another Celly 356. Couldn't pass up a $15 server pull.

Would you do this outside of binning chips? The mass of my pot is pretty absurd (3.65kg, otternase makes em big), so cool down seems like it will take a while; i haven't used it yet so don't know but something says 8lbs will take a while. I know it's a big sucker to drop on and off, but if i can keep that pot at a lovely -190 (which should be no problem as long as i keep it full, and i can drip it right from the dewar into the pot) and pull it off for booting, it would make taking the torch to my very expensive pot less needed, even though i know it won't damage the alum or copper, just wastes ln2.

Actually the continual cycle of heat up and cool down does something to copper which makes it more responsive to ln2 over time. I've seen it for sure with my F1's. My first pot which had serious usage gradually became more responsive. When I switched to a brand new F1 I could totally see the difference. Now the new F1 is starting to get responsive after the abuse
K|ngp|n has talked about this wierd effect a few times now.

honestly I would just strap it down, doesnt take that long to do. It was good when I had rom's koolance pot so I could thaw one while I cooled one.
Best bet is to buy a known good chip like you are doing

I've heard those guys talk about that too and I don't buy it.
I call it familiarity. Use something for a while and you get comfortable with its quirks.
I also don't buy that "glazing" your pot hocus pocus. After you've been benching for a bit, you've equilibrated your pot temps with the insulation and hardware around it. Means there is less of a temp sink that absorbs changes and your pot becomes more "responsive". Reaching that point often coincides with having reached a coldbug and needing to torch. Thus the association (in my mind).
But hey, I'm not one to bash established dogma and superstition. I like benching with an anvil nearby. Whatever makes the stars align in your bench session is good.

I can see it, LN2 is cryogenic temps, and cooling and warming metal through such temps changes the crystal alignments.
They do it to competition rifle barrels to line all the crystals up and get that last .1% accuracy. I don't see why it couldn't do similar things for heat transfer.
