Calling the balk with R3

[fwump]

I am on board with the concept of "preventitive umpiring". And I'm getting the idea from the feedback here that age level does matter to most of you guys when you are faced with this sitch.

Lets say you are doing a HS varsity playoff game. Tie game bottom 7th with R3. F1 comes set and does not come to a full stop but it is close. Is your thinking here going to be different? Are you willimg to balk in the winning run on a not very blatent balk?
