Disclaimer:This is based on my personal opinion

1st Pick: A double Recessive male. You could produce pin double hets, giving you some really cool stuff in the future.

2nd Pick: Albino or Spider albino. Giving you codom hets that you could use. Albino Spiders, Pins and Spinners are awesome.

3rd Pick: If you want to see visuals in your first breeding, than i suggest getting a cool codom. Ie Banana. (Banana Pins are slick)
