I just started a few weeks ago updating my jig collection. I find the most important thing to look at on a jig is not the name but the head style / shape. For instance, I wouldn't use the same jig to fish around rocks and boulders (my preference is a wide-headed jig that won't get stuck in crevices) as I would to fish grass (either a pointed head jig or a narrow banana style head that would come through weeds easily). Rather than thinking of them as only being used the way they're named, don;t even pay attention to the name but the style / shape of the head.
