Wow, that sucks! Must be a crappy box given my experience with them.
Last time I had a P short was '07, but I remember them being just ok. I'm all about half coronas now; would buy them over any other small sticks. Thinking about putting five boxes away for a couple of years, but would need to pick up a couple more to smoke now. Hope the weather gets warmer soon so I can start smoking other stuff. I have some Monarchs on the way that'll probably take their spot.
I had a couple of '07 boxes of PLMs a while back that were nice, but they're long gone... Had a '10 PLPC last week that was nowhere near ready, so if you, or anybody else has some, I would recommend not even bothering with them yet.
Demi tasse is a lovely smoke. You won't be disappointed if you break into them
