I did some serious time on the B734. IMHO you were absolutely 100% right. Get the altitude. In order not to exceed flap speed with only 15° pitch up, you need either retract the flaps quickly og reduce power...not so good option in windshear conditions.
If memory serves me correctly the F/D directs you to maintain speed up to v2 + 20, any less speed will be maintained down to V2.
So, let him bark.
