The Nano mold is a snap to shoot and the bait is a super ice bait. Its also great in just cold water situations like early spring [immediate post-ice out] and late fall. The multiple color Nanos are challenging simply due to the small cavity sizes. It also requires very specific SMALL pour and control capability and a small spoon fits those needs very, very nicely. Because the bait is quite tiny, the color intensity of the plastic needs to be increased but the results you have seen in the pictures here.
As soon as you get your Nano mold and feel like you want to step into that rewarding realm of working tiny, just give a holler and we can get some real specific pointers to you that will shorten the learning curve immensely.
