I am looking at purchasing my first snake from American Made Exotics, they've been super helpful and reply to all my questions promptly. There are a few snakes of theirs that I really like, but I'm not very sure about the genetic aspect. I am not interested in breeding (ever), but I have heard that certain genes can come with wobbles and other issues, and while that does not mean that it is an unhealthy animal, this is my first ball python and the less problems it may have the better. Here are the genetics that I am looking at, is there any heath / neurological issues associated, or combos that I should avoid for health / temperament issues? Right now none have a wobble, but I have heard that that can appear as they age. (I included the genes of the parents if that helps)

1. pastel 50% pos het pied - sire = leopard pastel het pied , dam = normal
2. yellowbelly - sire = yellowbelly enchi, dam = normal
3. mojave - sire = Mota / Cinnamon-Mojave / Pastel-Spider, dam = lemon pastel
4. pewter - sire = Mota / Cinnamon-Mojave / Pastel-Spider, dam = bumblebee

Thanks for all your input!
