I am not sure if they are the same, I am betting they are along the lines genetically as Lesser is to Butter, Cinny is to Black Pastel, that type of relationship. that is purely my opinion. and not fact driven or backed up with any breeding.
I have a Lace Black Back from Tim & Het Red Female from Justin McBrayer (Thanks guys). I hope to have that cross in 2012, the Lace is pretty close to size, by the end of the year he will hopefully be ready to go, the Het Red is around 500gr, so I need another 1000 on her.
Het Reds & Lace's are not that pricey. Add the pastel or other gene, yea, they start to add up.
