Black Diamond Black Gold Loose Chalk

I bought it with some suspicion, but was drawn by the fact that it doesn't use drying agents.

Pure chalk that kept my hands dry for 2 hours of climbing in humid singapore weather. Not for those who chalk compulsively for psych.

I bought this chalk a few months ago and saved it for really fingery/delicate and condition dependant projects.
Well, after so many uses, and comparing it to other chalks like the normal BD's, on the same day, between different tries on the route, I could not see a great difference:
- It didn't really made me chalk less, or made me feel less humidity on the fingertips, the sensation was almost the same.
Although that, it's a great chalk, yes, but does not deserve the mega price difference, and propaganda.
