2 man fly ball mechanic question

[bisonpitcher]

How do you guys handle the fly ball to the right side of the infield as a BU in A? Some guys I work with like to have PU take all fly balls on the infield and have the BU pivot inside, others like the BU to stay near his A position on fly balls to the first and second basemen and take the catch/no catch while the PU comes up to take the BR to second if the ball is dropped. Different mechanics manuals and sites I have seen state differently on subject.
