1) the aircraft on G/A does not automatically change to CLB from SRS. You need to pull >> that gives you time to think what comes next.
2) Answer to Q: Pull speed, 160 kt. Or less, down to Vls as needed. Vls for 1+F is exactly that, so use it. Or Vls+5.
PS: maybe I sense some confusion between "S" the minimum speed, at which the flaps may be retracted after takeoff / GA, and "S" the (convinient) target approach speed forconf 1+0 ?
Some companies advocate not flying below S speed on approach with 1+0. they ask for CF 2, they have their reasons. But flying below S speed with 1+F is normal, just like we do for take offs. *

last time I tried the V2 was 159, so at V2 +10, not that slow at all
