Carolina rig

Yay or nay?  If yay, when and where do you use it?

I've had some luck in past years dragging a zman craw on St Clair, but have never really put serious time into learning it.

I use it to cover water. I use it often to follow up after finding bass and catching them first with a crankbait. I like it around moderately heavy weeds. I sometimes use a jig for the 'weight' to occasionally catch 2 at a time! Good technique for people with less patience.

I use it when I can't fish a drop shot (in Michigan, that's rivers and drowned river mouths)...

Actually, it's a better bait for covering water, as Dan noted, than a drop shot.  It's fantastic in hard-bottom lakes with milfoil as it's can get down in between the stalks. Sometimes it will catch fish swimming the lanes in those weedbeds like nothing else can.

Lightweight c-rigs on spinning tackle had done well for me in the past. In recent years, I tend to use either a jig or DS in those same circumstances where I'd throw the c-rig before.  I probably need to get back to the C-Rig.
