Hope i'm not side tracking but may i suggest sugar. I like sugar more cause they are more consistent in the middle of the amount of white that show where as calico it tends to either be high or low white. But i do like calico so go either way i guess.
I just took and uploaded these pics of my sugar bee.
Out of my whole collection i needed some updated pics of her the most next to my albino boa who is overdo for some new pics. Can you believe i only paid $225 for her. The seller claimed he made a mistake in posting the price and honored the listed price. I'm not a genetic expert but i do believe she is a sugar.
