You would get all mack snows. If your geckos have any unknown hets, then you may see some other trait pop up. It's a bit counterproductive to breed a tangerine with a snow.
I would recommend doing some research and getting a few geckos of your preferred morph from a reputable breeder and keeping the ones with unknown genetics as pets.
Right now is great for looking for some leos from good breeders since the season just ended. I couldn't tell you what morphs to get because there are a lot of them and it is all based on your preference.
