I was planning to get 7 cakes of Menghai 7542 batch 901 from Dragon Tea House. I had their Menghai 8542 of 2005 and I like it, plus I read that 7542 is a standard in the world of puerh. The 2009 is quite cheap now and getting a fair amount seems like a good way to make sure that some of it will be around long enough to age.
Does anyone have particular suggestions? This would be my first purchase of more than one cake at a time and I am sure that many of you who have much more experience might have helpful comments

Thanks!
