I brought it home and got great results from a gaiwan.
But... now that I think about it, I used up the last of my TPHK on the shibo try, and there was a lot of broken leaf in there that I did not clean out... so it may have been that. And unfortunately... that also means I can't try again!

Although, as I said, this TPHK was a really tough customer for some reason. I don't think I've any other tea that I bombed out that much on...
