I think the only way I can truly learn about pu is to try it! So I'm prepared to spend

I've been searching through Yunnan Sourcing LLC for a variety of "experiences" and come up with this list:-
1998 Lincang "CNNP Green Wrapper" Raw Pu-erh tea * 250
Its (a bit) looks nice and is described as "a real pleasure"
2000 * Long Yuan Hao * Yi Wu Shan Pu-erh * 25g SAMPLE
To compare to CNNP green wrapper above.
2007 Mengku * Spring Tips * Raw Pu-erh Tea cake 400 gr
Its young and "challenging"
2008 Menghai Tea Factory * 7532 * Raw Pu-erh Tea cake
To see what a fresh new high quality sheng one is like.
2004 Xiaguan Bao Yan "Tibetan Flame" Raw Pu-erh Brick
'cos I've always wanted to make tibetan butter tea properly
2008 Lao Ban Zhang Wild Arbor Pu-erh tea cake * 250g
compare to 7532 - and it sounds banging
2006 Mengku Lao Ban Zhang Pu-erh Tea cake * 100g Loose
To compare to 2008 Ban Zhang
2000 Langhe Tea Factory * Aged Ripe tea of Menghai 357g
'Cos I love shu too
A wide variety I hope. Expensive in total but affordable.
I realise I could buy more samples instead to save money, but I have found that I usually need more tea to learn and appreciate.
So any comments on my choices (and approach!) ?
(ps the tea titles are the exact heading from YS pages so google should find them easy if anyone wants to read more)
Happy cha
