I have been fishing a crig for about 15 years. Mostly on GA reservoirs and now I live in SC and fish Lake Greenwood. The crig is my favorite way to fish and here are my reasons:
It's generally slow and very relaxing. My friends will cast their baits 10 times to my one, I figure between the two of us we're covering the water.
It is pretty consistent, I feel that if there are bass in the water, I'll catch a couple of them.
You can learn a lake very quickly.
A strike is almost as fun as a topwater strike.
Some are having trouble casting, remember to cast the weight, not the worm/hook. I use a baitcast reel, can't get a spinning rod to cast well with this rig and I also like to control the cast with my thumb.
