The method you mentioned below, means i wont have to fly anything at 90 degrees at all? I will do your suggestion at 70 Degrees camera angle to get more tree information. N-S AND E-W.
Any ideas for Ground Sampling Distance (GSD)?

Very nice Golf! and well located! Back in the time, I visited Mainly, it is really nice!
To map this Golf, I would recommend you to go for a double Grid, having a tilting angle to get as much information under the trees. Note that the double grid mission cannot be flown with polygon shape.
It would be maybe more suitable with the city airspace restrictions to fly two single polygon missions. Having the same settings (overlap, fly height, tilting angle, size…), one would be flown with flight lines pointing North-South and the other with the flight lines pointing East-West. It would be the equivalent of a double grid with a polygon shape"
