best a/b exraction?

[OzzBozz]

SWIM is interested in attempting a a/b extraction and yielding a good quantity of spice.

Whats the best a/b extraction? SWIM may be confused, but there are so many different DMT extractions... is there only one true a/b extraction?

SWIM would like to try the extraction, as i hear you yield great quality white-crystal and you get the most band from MRB compared to other extractions. SWIM and SWIM'S pet farret are both interested, and both have a good knowledge of chemistry and have done similar extractions.

Also, does it matter if SWIM uses powdered IMRB from a reputable source???
