#10 North Tukvar is most likely Mariage Freres. I've only seen this tea on their website. As for the FF Darjeeling recommendations from Mariage, like I posted above, I would say Narming and Namring Upper. I have not yet tasted some other MF FF teas I listed below
Since I'm all out of all Darjeeling teas, I plan on sending my order to Mariage France for the following:
FF Namring Upper
When I'm in Tokyo later this month, I'll probably purchase the FF Ambootia and FF Happy Valley from Mariage in Ginza. I'll pay a large premium, but as you say, they never disappoint.
