I've used the Primos Gen 2 Jim Shockey edition tri pod trigger stick. Very smooth, easy to use, they worked great. That is until you get them wet. Went through 2 sets of them. The second set lasted longfer than the first set as I made a good effort to keep them from getting wet. However sooner or later you're going to be hunting when the dew point reaches that level where your sticks get dew on them while you're hunting. Won't use them again. I now use the Bog-Pod tall camo tri pod shooting sticks. Not as easy to set-up as the Primos, but still easy to use, light weight and reliable. I set them up for a standing position. Most of my pig hunting is done at night and I almost always shoot from a standing position. With what ever rest I'm using, I've found out for me, the farther out on the forearm I rest my rifle on, the more stable my rifle is. To me a tri-pod is a much steadier rest than a mono-pod or bi-pod.
