Block...or not....

[refnrev]

Jan,
I'm not arguing so don't think I'm being a jackass here. I do some really good schools and it's a sincere question with which I am wrestling and want to "own" this rule next season to be the best official I can be. Three scenarios are running through my head:

1. Girl's hands are above the net in blocking position. Ball is below the tape on top of net. She reaches down and contacts the ball below the tape. Block or 1st hit or great possibilty of illegal hit?

2. Ball crosses net as front row player is near the net. Contact is made after the cross and ball is below the tape. Block... or first hit?

3.Quoting Felix: "However, a blocker is also defined as being "close to the net...'" She's close to the net but feet on floor with (A) arms extended over her head or (B) Arms not extended ... when contact is made. Ball is below the top of the net when contacted. Block... or 1st hit?
