Haha, until I saw your last reply...
Using the possession tactic at the moment and a suggestion is to add the instruction "sit narrow" for the IF & the wide AP. I have seen it keeps them closer to the play when the ball is coming through the middle, and gives them the option of going wide or running through the middle.
Funny you should say about the above, I've had a few attempts at creating a tactic and all have failed, we know the beta is bug ridden at the moment, but well done on being able to throw something together that quick.
It would be great to keep working on your possession tactic, as I love the play and dominating the ball.
Good stuff mate.
