Difficult Situation #2: Line Drive tipped foul by F5

[AtlUmp]

Come on now..The PU should already have "picked up" the ball when it left the pitchers hand, and when it changes direction it will be going pretty close to straight away from him. You should be able to see the ball while getting out of you're crouch and the mask shouldn't be a problem. You can delay removing it for the second or so it takes for this play to develop. This is the PU's call and one he has to make because the BU does not have a good angle, looking through body/glove of F6 and he would also have the same timing problems you described for the PU with a much worse view of the play.
