1) Stabilise early
if managed speed target is much above 160kts select speed , just to stay away from vmo in case a sudden increasing head component and hence increased mged speed target led to an overspeed. manage it later when you calculate it to be about 160 ( you need a bit of capacity for that but stablising early will give you a bit of time)
2) use f3 even when w/s not reported on atis but you suspect it to be a rocky approach
3) my experience has been a/thr on with rolls royce and a/thr off with cfm
the fadec should mean that the engine type is irrelevant . nevertheless it's still my observation and practice.
