It's a great head, so think twice before replacing it, as some photographers will do when the 'newest' or 'greatest' comes along.

After all, just as the venison on the table that never cared how fancy or exotic the gun that caught it was, a solid tripod head, compared to another, does no care what's newest, as they can all have a limit to how strongly they hold the camera they carry and how well.

IMO.
