Yeah that thread is awesome! You did good work.
It's of course relative to the situation and piano, but I think it's awesome that the winner was the cheapy modded mic!
BTW, SDCs can get good sounds too...I have used both for different reasons. In a couple of weeks I'm recording a critical solo piano recital and I'm going to have a Blumlein ribbon pair and a little farther back a pair of Oktava 012 SDCs.
