is there something i can refer to when looking at MD.
they always have different colors in the rock.
there is light transparent one yellowish, dark coloured ones with very purplish tinge etc, yellowy tinge yellow rocks.
the question is, which ones are better? lighter or darker etc. or what is the general basis.
Thanks in advance
You need to try out all of the different colors. You will need to take pictures of all of the ROLL faces you get from the various types of MDMA. You will then need to go with the type that gives you the most fucked up ROLL face ;-)
