A good way to fly winch is to just use lots of elevator to control the speed at about 70 kts (50-60 kts in a slow glider), looking to the side every 2 seconds to check wings level. If the rope breaks, push the nose over immediately until you are flying the same angle below the horizon that you were above the horizon when the rope broke, until you get to flying speed again. Then level out and release the rope
Flying winch in Condor is easier and safer than in real life, probably because the engine never has issues and it's always driven with high tension. So best to practice everything correctly in Condor even if it doesn't demand a lot of you. Here's a winch flight manual that was made mostly by people from the British Gliding Association and adapted by our club.
