I've watched Kelly Galloup's video on the Drop Shot method. I have also listened to George Daniel (at a conclave) talk about the same type of rig - split shot on the bottom of the rig. He never mentioned it before, because he use to be involved in Competitions. Now, his talks include using split shot. Especially, split shot on the bottom of the rig.

Here are some videos that show similar rigs:

I'll be trying Kelly Galloup's Drop Shot method this year. Darn, I have to fishing again!
