I had trouble with it too....
I remember learning to fly stall turns. I was always shy of the vertical coming down, and tended to pull out too early. One time I was just about to pull out, when the instructor took control and said "That's not vertical - it should be like this!" and pushed on the stick to pitch us down. He then made me look at each wingtip in turn before recovering. I remember looking at them thinking it was the last time I'd see them still attached to the fuselage!
The wings didn't break off, of course, and we didn't even exceed Va in the pull out. If your downline follows an upline, you'll be starting it with a very low airspeed and you have lots more time than you think.
Takes a bit of getting used to, though!
