So my kings are getting older so I thought it was about time to start looking for heirs. Thing is I have too many options on my plate. I apologize for no images but I'm on mobile and it won't let me download demo images as it downloads a blank image and it won't let me screenshot it either so demo links it is. Feel free to play around with female versions of muts and poses as I can get a lab test frog for them.

My current king is this guy.

I did just get a g3 nrlc who's never been hunted or bred and is under 3yo, the only thing she was missing was the base and skin. I can gender change it and make it my heir. The opacities of the marks are different but could be made exactly like the rl via opacity changers.
Standard opacity
Opacities changed to rl opacities
The base it got is an uncommon rarity cloudburst factor but I do have ankh, hyena, hibiscus, atlas, ivory, and decennial base apps. I could also do a trade for arctic though ice or glacial could also work..
with Arctic and opacities changed
My question on this is do I keep my current king's looks and just change his mut or go for the nrlc? If I keep my current one's looks, what mut should I go for (I have mods for fringe, tobiano, panda, ticked, and overo and could find g2s for others)? If the nrlc, should I change the base and/or mess with the opacities? What should I mut rep with eventually if I go with the nrlc?

My side king is a g2 broken pie, I plan on keeping his appearance but I'm not as sure about the mut. I think I like Ferus, Felis, Tovero, or Svelte best on him but I'm open to suggestions.

Let me know what you think.
