I feel quite comfortable with my collection right now. I have...
- 120ml modern Hong Ni pot for everyday light to medium rolled oolongs.
- 40ml '80s Hong Ni pot for expensive light rolled oolongs like Da Yu Ling.
- 40ml '80s Muo Lu Ni pot for medium to dark roast rolled oolongs.
- 65ml '70s Hong Ni pot for Wu Yi oolong.
- 110ml modern Hong Ni pot for cooked puer and loose aged sheng.
- 150ml late 60's Zi Ni pot for young sheng puer.
- 90ml porcelain Gaiwan for Dan Cong, Oriental Beauty, Bao Zhong, and expensive aged sheng puer.
- 120ml Tokoname kyusu for green and white tea.
With this set up, I feel quite able to cover all my bases, however I have
no doubt at all that quite a few more pots will be in my future. My collection feels incomplete without some vintage Zhuni, and I would like a pot to dedicate to aged puer too.
The best advice I can give you, especially because you are self-described OCD, is to avoid cheap pots! Save up your pennies and go for the good clay. Otherwise you will probably end up replacing them in the future anyway.
