While I really don't know for certain regarding the Ringer's cover, I will state that it does handle more volume than the Strike King. Even with my Ringer pin up, and my Strike King pin down, the Ringer does read the mid-lane much better from what I am seeing.
The Strike King could be more angular due to the fact that it goes longer, and once it finds adequate friction, seems to respond fairly quickly. Our eyes see the late movement easier than what the ball does mid-lane, since it hasn't changed direction much yet. Nice observations here. Thanks to all.
