Brindle and tigers are best to pair with another brindle or tiger. With or without portholes
Dalmatian I think goes best with patternless/phantom or another dalmatian.
Harlquin is best bred to extreme harlequin or tricolor (and stay away from full pinstripes, they can mess up harlequin and tiger).
I think both cresties you’re looking at are nice! They both have “vertical lines” and similar base colour. What would you like to produce? Any morph/colour you fancy?
