I know Im repeating some of whats been said, but Ill still throw in my $0.02.
Ill also add (coming from my limited experience buying, breeding and producing het red combos), that the two names being commonly used are gargoyle for cinnamon x het red combos and onyx for black pastel het red combos. I have very rarely seen a cinnamon x het red labelled as "cinnamon het red" and I have NEVER seen a lace black back x black pastel being labeled as a "gargoyle". All the gargoyles Ive seen for sale have been cinnamon x het red. Until today I didnt even know WOBP had a gargoyle labeled as something other than a cinnamon het red!
