Simon Lorenzi's story sending Soudain Seul (9A)

Simon Lorenzi made the FA of Soudain seul (9A) in 2021 after 25 session, including just two sessions on the standing start, The Big Island (8C). In the end, he needed to put a book under his knee pad in order to improve a knee bar. Here is how he answered our questions after the FA.

How hard do you think both parts are individually?
For me, it is a hard 8B (like harder than all the 8B I did) into a hard 8B+. But it's weird because this first part is so conditioned dependant. With 12°c it felt way harder than the second part and then if it's between 0 and 5°c it feels like 8B.

How good is the hold in between? Can you chalk there or somewhere?
All the way to the top without chalking up :) So just chalk up once before climbing. The end is complicated on the slopers.

Did you make a replica or just train at the site? What was the key for eventually taking it down?
Training at the site mostly because it's tricky and if I don't try it for a week I lose the feeling. Good short résistance and optimise every detail to spend less energy.

Did you have to use any special tricks being just 168 cm tall, beside your +8 cm ape index?
1: Using stiff shoes instead of soft shoes to put more pressure into the kneebar.
2: Using a stiff kneepad with something under (I first tried with old chunks of wood).
3: Stretch my upper body to gain mobility. Like that, I improved my arm reach a bit.
4: Using a different beta for the crux of the stand start.
