, check my post in the "worm rigging" topic in the bass forum. I gave the details of a rigging style that was very effective for me. I used that rig in a gravel pit pond with much success. It worked so well that I stopped using all other rigging methods and just used it. I rigged it with a four inch Creme scoundrel worm. I fished it very slowly and tried different depths, starting shallow and working down until I located fish and then fished that depth. I used a slow stop and go retrieve either unweighted or with only just enough weight to get the worm down to where I needed it. As for color, that might vary due to water clarity, time of day, fish preference etc. but the three colors I used were black, clear purple and natural. The natural worked the best for me. WalMart carries the 4 inch Creme worms in this color but I'm sure you could rig most worms this way. Use straight shank hooks and I would recommend using a swivel tied on about a foot or two above the worm to reduce line twist.
Just a suggestion but I thought I'd mention it to you.
