I've been doing a lot of research, but couldn't find a definitive answer.

I saw tight lines for crappie that look basically like my catfish staging...weight on bottom with two loops coming off for lures.

I've also seen people simply vertical jigging as "tight lining" em...with just a jig on the end of the line, slowly lowering it to the depth of the fish.

My question is...which of these two are what people mean when they say theyre using tight lines for crappie?
