Sweet!!! I knew it would work out for you. Pretty much you need to do that with all Nakhla, its dry and heat sensitive. As a rule of thumb I do that to all my shisha and it seems to work wonders for me, starbuzz is the only exception though. I can put on 3 coals and leave em until the bowl is finished hehe go figure. Keep experimenting with different brands to see what works for them, I used to keep notes on all the brands and flavors when I first started or tried a new brand.
The greatest obstacle to discovery isn't ignorance, but the illusion of knowledge
