I installed a boomkicker last year. It has been great. And you can't find a simpler design. They are also about as inexpensive as any solid vang running about $200-$250. I ordered mine direct from the manufacturer. They have a special model just for J30s that has the rods pre-cut to just the right length. One less step for you during installation. They provide all the hardware and tools you need (except the basic stuff of course). It takes about 90 minutes to install .
