Nomans tek is the standard STB (straight to base) tek and is proven. Tho when doing the tek, once you have the DMT i would not do the ammonia wash, i would however recommend one sodium carbonate wash and then at least one re crystallization.
Many people like Q21's tek but i felt sick from all the colorful text so ive not looked at it.
BLAB is the one i recommend, but that results in DMT fumarate Which needs to be converted to freebase (very easy) a method for this can be found in the forum using water and CaC03.
This is the method i would use and recommend, simply because it avoids using naptha and is what i consider more elegant chemistry.
With any extraction you want powdered bark. So if yo buy whole pieces you will need to powder it.
When comparing A/b vs STB extractions, it is in my opinion that an STB is faster but results in a less clean product. This time saved is negated by the need to clean the spice. With this in mind i consider the A/b and STB equally effective if done correctly.
Like i said... i recommend the BLAB and then a h20/CaC03 conversion to freebase. Once you have done this and have your DMT i would then look at how to make either Changa (dmt infused herb that also contains B. Caapi alkaloids) or enhanced leaf.
PS: Changa is the stuff your looking for
