do you guys like rattles on jigs?

Some do, some don't. I rarely use a rattle. If I do, I slip a glass worm rattle in the chunk or plastic trailer I'm using. I don't like them attached to my jigs. Just my .02 though.

I have been debating this with myself for years and have never come to a firm conclusion.  I guess if I was pressed to make some sort of decision, I would opt for rattles in heavy stained to muddy water and not for lightly stained to clear water.  However, I can't really say that I ever had a situation where I thought the rattles had anything to do with the fish being caught or not being caught.  Hows that for a concise answer (LOL!).

clear as mud...   

I don't for the most part. When your fishing rocks the lure itself will generally provide the "clicking" sound of a crawfish. Most of the waters aren't muddy enough around here to warrant a rattle.

I do use them for night fishing. Crawfish are more apt to feed at night and will hide during the day and I think the "clicking" noise is a more natural presentation.

I guess I would think of it like spinnerbait fishing. More noise for darker conditions than for lighter conditions and by that I talking about both water clarity and day light.

MHO of course.
