I was looking for FK2-DW. 19/10cm hands and claw/relaxed claw grip type.
Same. I also have Zowie FK2-DW and it is exactly how you described it. I believe that Viper V2 Pro or something else low profile would also do the job. Handling, skates and micro corrections are great because there is no higher part of mouse that is hittnig my palm when I move it. Claw/relaxed claw grip.
Fk2dw calls your name
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. Itās going to be your favourite and best performing shape. If you donāt 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!
Best mouse i have tested so far i keep going back to it even if wired. At the moment I am with fk2 wireless because wanted to test docking charger that kinda improves wireless weakness. But really love. Op1
I have your grip and use the GPX 2 with no issues. Currently trying the Fk2-DW with this grip and also have very little issue.
You could try one of the HSK G-Wolves [https://shop.g-wolves.com/collections/hsk-wireless-mouse](https://shop.g-wolves.com/collections/hsk-wireless-mouse) to see the smallest it literally can get. These are popular with a lot of āaimersā who aim train a lot because you can articulate it more like the way you write with a pen. I tried them and hit some high scores on scenarios where you track a bunch of balls bouncing wildly across your screen. But I found with spinning my character 90-180-360 at a steady rate for tracking close hipfire on someone moving a consistent speed, I could never glide multiple inches across the mousepad at a consistent speed because the feet that make contact with the pad are four little dots instead of a larger smooth surface that I could feel gliding. None of this will be relevant to you if you arenāt trying to play ranked FPS games at a high level, of course. These are called fingertip mice and as far as I know they will all have a decent hump since at that size itās the only way to make something you even can grab onto well. Which is also a reason why the hump might not bother you like it has on large mice. The non-pro HSK is $70 on Amazon I think, with free returns if you don't like it. I ordered literally 20 mice for $3000 one time, tried them all for a month and returned all but one for free back to Amazon. lol. If this specific one doesnāt fit you for some reason, searching āfingertip mouseā will turn up a lot more results that you arenāt going to see in a thread like this, and wonāt get brought up in ordinary mouse conversations generally, but are often extremely good and loved like crazy by the people that use them. If I ever find one with smoother larger feet that let me slide it inches across the pad at a steady pace comfortably, and still give me that extra articulation, Iāll never use any other mouse ever again.
I keep a glass pad on the desk next to me, and swap it out occasionally :) The main I ended up with is the Fnatic Dash 2, which is definitely cloth and not glass, but probably about as close as you could get to glass with a cloth. I do think the glass feels better paired with the fingertip. I like the FK2-DW largely because of its low profile (the mouse buttons in front are very close to the ground) and lack of hump, funny enough (though it would surely be too big for you), so I basically rotate between an FK2-DW on a Dash 2, and an HSK on a Wallhack. Aim training with the HSK definitely helps transfer over to improving my aim in general! If I jump by 100 points after an hour practicing with it my scores will still be up by 70-80 points or so when I swap back over. 360° tracking just always suffers and I find consistency with that too essential for the FPS Iām playing. If a game required extremely fine and fast control of aiming at whatās in front of your face without ever having to turn to the sides I would be a monster, lol. But games that donāt ask you to spin around much are tac games like Valorant that want a different kind of aim. Keep in mind that G-Wolvesā customer service has... not been reviewed well, which is another good reason to go with the Amazon affiliate, although that stops you from trying their slightly better and āProā options. Can always try the Amazon one, and if you commit to their shape but want it a tad even smaller and lighter etc. return it and buy a Pro version directly.
Iād seriously consider Zowie. Maybe something like the fk2-dw would be relatively close to the model O, just a little flatter maybe. Could consider the S2 if you want something a little taller and bulkier. The zowie mice have optical scroll wheels which is the absolute best in terms of durability. There are very few other companies that use optical scroll wheels. Fair warning, these wheels are loud and extremely notchy so, thatās a downside if it bothers you but itās very unlikely they will ever fail.
