Hello all. Hope a forum member could shed some light on this topic for me. I have a Vortex High Country tripod. It came with a ball head but I would rather use a pan head. I just purchased a Slik 707e pan/tilt pan head to replace the ball head. My issue is the once I removed the ball head, the thread size is too big for the Slik tripod head. Anybody know where I can get an adaptor to go from one thread size to another?
