Strong side on 2 person mech

[SOWB_Ref]

As a newly frocked Varsity official, I would like some suggestions on when you would go strong side as a Lead. Is it simply when you see players in the post (high or low) and the ball is clearly strong side? This is one aspect of my game I think needs improvement. One of my perpetual fears is going strong side and having the ball kicked back over to the weak side quickly and being out of position on either a foul or OOB call.

Thanks
