Hiya Elin, I am 170cm, and I used the right heel hook beta. I just uploaded a video that misses the sit, and has my kids screaming in the background :-), but it shows the heel hook beta that Helen is talking about. I hope this helps ...
Rain sucks, but broken holds suck even more. Remember, never climb on wet rock in Fontainebleau.
The sandstone becomes brittle, and pulling on it will ruin classic problems. Drying it doesn't help, because it's still wet and weak inside.
All you can do is wait for better conditions.
