-78C ACETONE/DRY ICE Bath for DMT Precipitation? Options

I am about to do a pull on a couple hundred grams MHRB and I am thinking about the "freezer precipitation". This is my first DMT tek, but I am experienced in the basics of A/B extractions.
My question is this: Has anyone out there tried an acetone/dry ice precip? It maintains a temperature of around -78 degrees Celcius. I used this method to collect NH3 and it worked fine. I don't want to go to the hassle of setting this up if this is unnecessary or counter productive.
Any thoughts from experienced extractors?

If you have a freezer that can reach -20 degrees C then use it. An acetone/dry ice bath would definitely work, but it would be unnecessary, and certainly more of a hassle. You could precipitate the DMT out of the solution in a shorter amount of time though.

The freezer precipitation works just fine, make sure its a cold freezer, stick a thermometer in there if you have one, and wait ~12hr.

If you want to skip the process entirely I would recommend a FASI precipitation. It is superior.

Thanx,I have a decent freezer,but I was thinking it would take days for crystals not hours. "Cool".
What is a FASI precip?
I found the FASA precip, still looking for FASI.

FASI is the same concept as FASA, only using dry isopropanol instead of dry acetone. I like FASI because isopropanol is much cheaper, so its cost effective for me.

Thank you, I'll look for some anhydrous Iso.
