Normally we talk about adding half the gust factor on the approach. I question that because on the approach its likely that the winds will be stronger than the reference point on the airfield.
Wind speed and direction maybe different.
We had a thread on crosswinds and rudder authority is required to maintain the centreline as well as control over landing.
It therefore stands that in very strong crosswinds you look at a different technique to landing at or near the stall but use a slightly higher speed for extra control and fly it on.
There are other considerations like the headwind component and runway length.
I have experienced + and - 25 to 30 KTS with shear so trundling down at VREF would be none to clever and speed management as well as reducing speed comes into play in those conditions.
Energy is your friend but you have to be able to control it
