It's funny. I work with both the VPI sugar and the NWE calico line and to be honest I've produced so neat looking combos using both lines. The one thing I can say is that the Sugars seem..that SEEM (with my limited production of them this year only) to be more colorful as base morphs than the NWE calico's. I've talked with breeder at length about their feelings on if the different lines are different enough to really call "different" and the response seems to be split. Some say yes some say no. Me I'm going to, for now, keep the lines separate and market them separate just for those people that want a VPI sugar or want a Calico..
