I did some of this alternately with fielders' shoulders. Better when fielder off to side. Still prefer the "line" through the pitching plate, rather than tangent to the circle.
The C2 did allow a better view of the pitcher being outside the 24".

Tangent? I was told there would be no math....

Sorry but I am a retired structural engineer, :p.

That's not math. That vocabulary. :rolleyes:

You guys are off on a tangent...

This is the way I was taught!!! Use your pitching plate as a point of reference in B and make slight adjustments.

Similarly, while in C, don't let the position of the SS take you closer to 2B than necessary. If needed, move to 3B side of SS. You don't want be caught chasing down an advancing runner into 3rd, you will end up getting straight-lined and guessing most of the time.
