Chuck - thanks for sharing, I'm watching your progress on the body-booting rig with interest. I've been thinking about making a few next year for open-water diver hunting next year when family visits. Most of the time I just layout hunt them alone out of my Momarsh DP, but can't do that with three, and I'm thinking this might be a way to get everyone out and involved. Like you though, I was leery of where the guns would be pointing if we turned the silos. This might work real nice. Please do post up some pics of it in action and whether or not it worked for you.
PS - Bob, the minis are cool!
