I sort of agree. All the ones I'm keeping right now, plus some I have to let go, I really like. I'd have to say, though, that the South Korean dione are my favorites, at this time, 'cus I really enjoy working with them, and they have such great personalities. If they were brighter colors probably everyone would want them. The conspicillata are really keeping me entertained too. I like the Mandarins a lot, TER, but they aren't as entertaining 'cus they hide so much.
For N. A. ratsnakes, I'm going to have to agree with T.P. that Great Plains rats are my favorites. There are many different localities though. I like the intermontana and the Brazos Island Rats the most right now. Also, there's a lot of potential in breeding the different morphs.
