Recommendation for my grip

So I’m looking for a mouse for my grip. I don’t know if there is a model where the side buttons are more rear sided.

The OP1 8k is also a little too wide for my preferences. I would like a mouse where the rear doesn’t have that big curve. I’ve tried the wlmouse beast x mini but I just can’t with the side holes.

I fingertip. My palm isn’t touching the mouse at all.
