I've mostly used ball heads, with a few exceptions over the last 40yrs, and 95% of the time they've been weedless style jig heads. I really wouldn't think there'd be enough difference in shape to noticeably affect the dynamics of something that small.
IMHO ... it's a lot like "eyes or no eyes" on a jig head. I've used both, simultaneously, and haven't seen any noticeable preference towards one or the other. The jig heads I use for casting purposes are unpainted/no eyes, and most of the jig heads I use for "pushing" are painted & some with eyes. I catch fish on all of them ... so I've come to the conclusion that head shape, like eyes/no eyes, is a matter of personal choice. What prompts that choice may be personal experience, recommendations of others, looks (in the eyes of a purchaser), or what you were initially taught to use by a mentor.
