So happy that you grinded that much, thank you!
4 hooks before the last long pole is also the best i can do, i think better is impossible, but mayyybe you can safe one hook right after the many wind-walls next to each other where you have to use many hooks in a row to get up, but im not sure lol
Also i dont know if you did this, but you can get 2 boosts at the same time if you fall exactly in the middle between 2 wind-walls at the wind-wall-wall™
And if you're at the final pole, hugging the wall and hooking with the smallest angle possible gives u the maximum hight (hooking exactly 90° up gives max hight)
-602 is still really really good, congrats :)
