Man, I really want that error #27. I think I might do it just for laughs, but I think I'd get cross looks from my dear sweet wife. I've been waiting on a #31 forever, and it seems like they're doing a #30. But they told me last year that the #31 was coming this year... and I couldn't wait. I ended up with a 12" All Clad D7. It is the freaking truth. I love it as much as my Dartos, and the fact that I can do acid in it without worry is a boon. It's thick as nards and weighs 1965g. Only 4.5 pounds, but because it's D7 the evenness and heat-up time are unrivaled [relative to cast iron and reactive steel]. I got a new open box one direct from the factory for roughly Darto prices.
I season mine with Bar Keeper's Friend because I like to ride eternal, shiny and chrome.
