I like to keep it as simple as possible because:
1) too many choices get confusing and
2) I just don't think it matters that much.
The most important things are depth and speed. Everything else is just window dressing.
That being said, I typically use a plain, ball head 1/32 oz marabou jig for crappie, usually with a red or pink head.
For bluegill, I usually go with the little 1/64 oz trout magnet heads.
With those two options, I think I could catch fish anywhere in the country.
