Fitting reversible gate hinges

[bemused]

I am having two wooden drive gates made, each one is about 1100mm wide (height about 6ft). The gate posts are 100x75 wall plates and fixed solidly to brick walls. I have 600mm reversible gate hinges to hang these gates, but in respect of the play in the hinges, I'm not sure how I should go about it. Should I:

1. Ignore the play and fit everything square.

2. Fix the hinge caps to the wall plates with a slight tilt, so that the hinges "rest" at the bottom of their play, with the main bar of the hinge horizontal?

My guess is it should be done as in (1) above, but if over time the gates drop, then they will take up the play in the hinges and sag in the middle where the two gates meet. I can't help thinking option (2) will keep everything square on the gates but not look quite right.

Grateful to hear how it "should" be done.
