I'm with GQ; climbing in FLC so just walk the speed bug up to Vfto when passing the acceleration altitude. If you walk the speed up slowly you keep a greater RoC while you accelerate. Probably FLC at its most useful.
Not too sure how you judge arriving at Vfto as the flaps finish retracting. Not a good time to be on the wrong side of the drag-curve if you misjudge it!
