This will potentially my first season to produce one. That's just what I've heard through the grape vine. I've personally never had an issue with a spotnose, but then again I've never owned a powerball. So I'm not going to speculate, just take his advice until I know for sure otherwise. To me it makes sense that lower incubation temps would reduce the chances of the possiblity of kinks, wobbles, etc. Not saying that any specific mutation for sure one way or the other has a wobble. I'm just saying that I'll be incubating mine at lower temps because of what I've heard.
