Variation or did I make an ID mistake?

[Lord Sorril]

If you were to keep one, which would you choose?

That would depend on the next morph target for the breeding project:
If the morph I'm trying to produce is going to be obvious-I would use the Reduced Pattern one to keep it clean.
If the morph is going to be a bit messy: I would use the one with the obvious head stamp (to increase the ease of offspring ID).
