I produced an 8 egg clutch last year. Out of that I got 1.4 spiders 1.2 normals. The one male spider had a pretty noticeable wobble when striking, he was also the last out of the egg and had the best pattern and highest white . The other 3 girls had a very slight wobble when striking but the holdback female (cleanest pattern) had no visible wobble even when handled. So in my experience/opinion spiders can throw babies who exhibit no wobble and heavy wobbble in the same clutch.
Pairing was a normal x spider. Father was the spider and showed a slight wobble.
