Looking online at the website, it does appear to be a very similiar design to the 1070.Rolled vs Cold Rolled ....
"Compared to cast iron or other common cooking materials, cold-rolled steel has a substantially better thermal conductivity and heat capacity per volume."
I'm thinking it's the same material as their griddle pans that they sell. I need to see the inside of the new griddle - what's unique about it except a full sized sheet of carbon steel? Do I just take out the shelves and drip tray and diffuser out of my 1070 and it's basically the same thing?
