Assume you are talking A320 series.
I would as per the Zurich requirements on the Take off perf page modified to have thrust reduction 2900' and 4500' for accel.
On approach leave G/A perf page as per your SOP so 2420/2420. I suspect the G/A path keeps you clear of noise sensitive areas as well as terrain (plus G/As are much less often so less of a concern for them).
