need help with mouse grip

I recently started trying out neon and I guess I wanna bind my scrollwheelup to jump with the spacebar, the thing is I have no idea what finger to use on the scroll wheel, my index finger remains on the left click and the middle finger onthe right click (the rest of the fingers just grip the mouse from sides) so how should I go about this? (Additional tips for learning neon would help )

I use scroll wheel DOWN for jump which should be better as well when playing movement agents.
What i do is index finger on left click. Middle on scroll and ring finger on right click.
This helped me better but again its subjective.

I hold my mouse like I goon

You can just use those, not like you are jumping and shooting at the same time, you can just use the middle finger to jump if you are concerned about shooting since right click doesn't do much

For me, I use my index since my ring and pinky gives me control over the mouse, I tried to use my middle finger on scroll wheel but it gives tension to my ring finger that can cause pain and uncomfort on prolonged use, although I highly suggest trying both like LowGun said it is subjective.
