I think this would go here, but I'm not entirely sure.

I'm having trouble choosing an heir between two lions I have at the moment, and I was wondering which would get me the most money from studding -

So, I have a beautiful, high stat (638) ferus boy with an ardor base. He has fifteen markings, one of which is DBR (dark brown rosette) on slot two with a fairly high visibility percentage, and seven of which are hidden. Cons are that he's really long gen and pretty dirty deep in his heritage, and probably won't live long after the time I king him.

Then, I have an absolutely gorgeous interstellar cub which I plan on using the ticked mod on and genderbending. She is gen three, squeaky clean, and pretty high stat as well (370). She's got breed only eyes, but only four markings. Only cons are that she'd have to be genderbent and worked on marking wise.

But I'd really just like ya'lls opinion on this. Who do you think would get me the most out of studding?
