Funny that you mention lower temps bc i remember someone saying on here before about how theres a possibility that the spider wobble is linked to incubation temps. And that cooler incubation temps would produce spiders with little to no wobble. I also remember someone saying that it was suspected Kevin at NERD knew how to produce spiders with little to no wobble but was keeping it a secret lol.
*In no way am i saying this is true. I just remember reading it on here.*
