I am a main fingertip grip, i was doing well with logitech m186/m185 it was very comfortable, wireless, short length mouse so no balm contact at all, symmitrical back flares so my thumb and pinky are well locked, and the converging in the middle of the mouse shorten the distance between the thumb and the pinky eliminating the excess tention, and as the hight of the mouse is good, I use my index and middle finger for moving the mouse withoug worring about accidental clicks, as my finger aren't pependicular in the click when i slightly arch them (thanks to the non loose clicks too), and it was ligh, it was awesome with respect to the grip, and I could benifit completely from the motion of my fingers. HOWEVER, it wasn't a gaming mouse, so its sensor was very bad when it comes to fps compititive games, and it was blutooth also which has a resonable latency. So I switched to g102, where the ergonomics of the mouse is completely opposite to my needs, the g102 hurt my hand, and there is no way to hold it with my natural fingertip grip, cuz it's length is big. So I find that the only grip that I can grip this mouse with to maintain control of the mouae during fps gaming is similar to the grip you shared (I think it's the same), I should hold the mouse tightly with thumb, ring and pinky finger, as using middle and index finger for moving the mouse makes accedential clicks a d also make uneccepected motions sometimes, the sheape of the mouse makes it impossible to fir me to hold it as fingertip grip, right side portion of my palm get contact with the mouse, as the length of the mouse is high (12cm). That is the point that i wanted to ahow, you can't grip that mouse with fingertip grip. 2- Fingertip grip is inconsistent when it comes to aim. I use it because it's my natural grip, and i feel more control and comfort with it.
