Hi all, tomorrow I will be going to Amsterdam for my 3rd time, but this time exclusively for finding the finest hash the dam has to offer

Im looking for the best, most potent charas (black hash) in Amsterdam but ofcourse if you know of any good moroccan, please don't hesitate to let me know!
As I understand these are the best Coffeshops for charas:
Blurbird
Kadinsky - trans himalayan
Greenhouse effect - black spice
and Rifman for Moroccan
Any other recommendations for an Amsterdam hash lover?
Thanks, peace & pot
