The new LC Signature line at WS is supposed to feature the new lids that have stabilizing nubs in order to help prevent rocking. I just noticed now that the new Flame oval I got recently from Amazon also has them too so it's not exclusive to the Signature line.
I was in Bloomies today for their sale and checked 10 or more ovens and the ones without the nubs rocked a lot less. ALL of them rocked to some extent, some more so than others, but the worst ones were the ones with these new nubs to help prevent that issue. Go figure!
I'm wondering if besides these new nubs the ones that have the new lid design also have the new enamel. Wish there was a way to tell.
