We use flaps 25° often, specially in winter when landing at BIKF , we can have winds up to 45G65kts and 160kts flaps 30° placcard spd,(VS 195kts flaps 25° placcard spd), may be easily exceeded ; the aircraft itīs more stable ,specially in roll , but in windy conditions with speeds up to vref25 + 20 you land almost flat with very litle ctrl input and almost no flare ,at 160 kts the 757 just wants to get airborne again.It works fine for us so far.
