It turned out pretty easy for me to get silkscreened white cross YFM and I'm not really sure if I want to buy red/black stripe one. I would rather consider these as /101 than as /21 and /80.
I guess my white whale record for now is Twitching Tongues/Ruckus split 10", it's very hard to find (/55 pressed) and it's the only thing left in my TT collection (along with some color variants though, but it's not a problem I guess)
