Ya that basically sums it up. Different names for different methods of extraction. Also different end products based on the method used, and the input material. Some techs and some materials result in nice golden shatters, some wax like products, and some will just turn to gooey oil. Lots of variables when it comes to extractions, and like was said alot of it all comes down to opinions and preferances. Some people like shatter, some like wax, some won't have anything to do with solvent based extractions and will only smoke hash that was dry sieved or water extracted. You know what they say different strokes for diffferent folks.
