FK2

I have tested now 68 different gaming mice, and I feel like my performance has been best with the Zowie FK2 shape or anything similar to that. I think the reason why I like it is because it is so low, long, narrow/curvy, it gives me good mouse control. I can comfortably switch between many grip styles on it. I dont feel like sensor positioning matters really, only shape, I mostly play TF2 MGE Scout vs scout

Reading the description of your problems, you grip your mice the same way that I do. Also, your hands are almost the same size as mine (19x10 here). Trust me and get the fk2dw. It’s going to be your favourite and best performing shape. If you don’t want to pay that much, try getting a second hand wired fk2 for cheap just to try out the shape beforehands. Thank me later homie!

Yeah use a zowie I have an old wired fk2 I use at work for the same reason

Its a lil pricey but seriously try the zowie fk2, I am also a finger tip grip style with big hands and was absolutely shocked how good the shape is on the FK2. After using both super lights for years I cant go back after experiencing the fk2

fk2 has a neat shape im similar hand size and grip style

Apart from clones, I find the closest one to the feeling of this shape is the Pulsar JVX because of the flat buttons and higher button height on the left click. But also the FK2 feels similar because of where you can rest your ring+pinky finger on the right-side of the mouse. The aggressive curve of the right-rear of the FK2 is close to emulating that sharp right-rear corner of the Roccat Kone, allowing me to curl and tuck-in my ring+pinky finger the same way. ULX Medium also feels very similar actually, it's like an ambi version of the Kone.
