Morning mate,
I read through your post and some things called my attention.
Over here in Brasil we don't have this TruBrake v2 mod but from what I got it's a softer spring, right? I conversely preffer to use a stiffer spring because our body memorizes easily the ammount of force applied rather than the distance covered by our foot. In this sense, I have a stiffer spring with two different elastic coefficients plus the original g29's rubber composite which I calibrate as follows: 0 for both linearity and deadzone. I adjust the saturation by pressing the brake until the pedal reaches the rubber composite inside it and moving the saturation switcher until the calibration reaches 80%. If I'm not wrong, for F1 22, my brake saturation is set to 40-45.
Still on the softer springs, you can increase the throttle linearity to help avoiding spinning. Or a stiffer spring on the throttle pedal too - which is what I've made. The effect is the same through different approaches.
As for the FFB settings, I use exactly the same, except for the wheel rotation which I set to 350. As @TotosHeadphones said, the FFB this year is lighter, but not so far from 2021 at all.
Bear in mind that this year the aerodynamics work differently, most of the aero support comes from the ground effect, this mean that one has an amazing grip on high speed but low speed corners, and more precisely their exits, are compromised as the wings don't provide enough support as last year so yes, the car this year feels more pointy.
You sound like a experienced player and I don't wanna sound pretentious at all but I hope this help you somehow.
Cheers,
Dan
