BD,
The boards we pull are custom made by Tim Adrien
http://monsterstripes.com/index.html you may have herd of him. I don't think he sells them though. The only thing about pulling boards behind the kayak is watching them. Keeping your head turned for miles while paddling is not the best for your neck. They create very little resistance, and the kayak is perfect for maintaining a good speed, not creating noise that may spook fish, and great control of your baits. I'm starting to really enjoy Striper fishing, and trying to learn as much as possible. I'm mainly a black bass kind of guy, but the linesides are gaining ground.
