The oriental games, hands down seem to consistently have the strongest eyeshine. That would be the asil, shamo, Thai, and Malays.
Where things get very special is when you cross the orientals together. Many oriental breeders are loth to do this, as the orientals are perceived to have long pedigrees of purity to their own subtypes. However, I subscribe to the theory that the more you mix oriental types, the more it puts them in a state of nature back to whatever the original oriental ancestor was.
Its the mixed orientals that I have produced that end up being more directly carnivorous and doers of unusual behaviors such as foraging/hunting at night and more recently, wading pond edges like a water bird.
