The thinking on the bypass was a bigger bore isn’t great with no spring, as the hall can wander too much. Too tight a middle piece controls the ball, but at speed would create back pressure. Hence the cage insert to control the ball, restricting it to linear travel, while allowing adequate bleed around it.
