Depends on your plans too. Pure hobbyist or are you planning on trying to make this into a business at some point as well? If you're just looking to make beautiful creations for you to enjoy and help pay for your hobby go with what strikes your fancy. If you want to try to see some return go with the new gene if it's something that you both like and think others will or may like. Also, 99.9% of the time new genes are BIG $ (unless your best friend proved it out haha) so you might want the 3 gene until you make a name for yourself and can both create and sell product. otherwise you end up with lots of mouths to house and feed. Not fair to you or your animals.
