For me, hands down, it's a C-rig (or its baby brother the split-shot). Everything from trick worms on light wire hooks to 10in. ribbon tails. I get more feedback from that big, heavy weight. My worm stays on the bottom or just above it and I can cover a lot of water fairly quickly with it.

I will use a T-rig with a 5/16oz. tungsten weight at night only because bites are easier to detect.
