Spider, Woma, Hidden Gene Woma, Champagne, Super Sable, and Powerball have been reported to have the wobble.

From the multiple people I have talked to to, it appears to have random frequency and severity at any age. So far no one has shown any link to the parent's frequency or severity passing to the offspring. However people have reported increase severity during handling or feeding. I have seen cases where the severity could be reduced by offering the snake a lower stress environment. So from what I have put together, stress or excitement plays a factor in the severity of it, but it is not the end all factor.

Another thing that affect wobble is temperatures.
