You don't mention which aeroplane this is for, so at risk of leading this thread off at a tangent......
For the B737 the windshear escape manuoevre is TOGA, keep the configuration you are in, and pitch up to 15° (Which approximates to Vy IIRC)
For the GPWS avoiding ground contact manuoevre it's as above except you pitch up to 20° (Which approximates to Vx)
I would be surprised if your type asks you to go to the edge of the stall as you will have no protection in the event of any gusts.
i miss the airbus.
If I was in windshear so would I
