The settings and why.
First, you have to always have your middle fingers above R2 / L2 and your index fingers above L1 / R1.
Stick lift, Puck Lift, Dash & Stop must be binded in R2, L2, L1 & R1.
Personally, I have Stop on L2, Stick lift on R2, Puck lift on L1 & Dash on R1 but it’s up to you.
Then Camera Flip must be in Square or Cross, why ?
When you have the control of the puck and you want to Camera Flip, you have to release your thumb from your R3 analog or your character will do a 180° with the stick and he will shoot the puck and you don’t want to do that, you want to control the puck again. Square or Cross is near the R3 analog so you can be fast with the transition of the camera then take again the control of the puck with R3.
With these settings you can do all the mechanics comfortably without sacrificing actions or doing weird things with your fingers.
