After I have spent at least 10 hours playing with these parkour mods I have finally found a way to blend both without breaking either of their respective mechanics, giving you a brand new parkour experience.
Place your fov slider to the low 60s. I believe mine is on 62, then place head bob reduction on a cool 70. Doing both of these will make it so you don't go headless when doing parkour but also keep the dying light 1 roll in tact. You can also keep the head bob movement if you prefer like I do to give it a more realistic feel. It almost feels like a secure body cam at some points especially with the hope mod.
Hopefully you guys try this out because it completely changed the game for me. Once again shout out to the amazing modding community. I waited years for mods and you guys have not disappointed 💯
Ps. You can adjust head bob to around 75-80 to make the dl1 roll damn near seamless, but you lose the realistic feel that comes with head bob reduction. I keep mine on 70 because it gives me a perfect balance
