There's only one perfect ergo mouse, and its name is Vaxee E1.
I have the same size hands and had almost the same problem with the same mice - aggressive claw grip so no pinky dragging, but I had to curl too much for the HyperSpeed. Landed on a Vaxee E1 and it fits me perfectly. It and the Zowie EC2-DW its shape is based on are worth checking out. The E1 sometimes does feel a bit short in my hand, but the EC2 is supposed to be a bit longer so it might work better for you since your grip seems and sounds a bit less aggressive than mine. Consider nabbing them secondhand if the price is prohibitive (they pretty much don't go on sale ever). edit: Also important to note those Deathadder shapes you tried are based off the EC1/2, so it'll be a familiar shape to you.
have the DAV3HS and had the same issue with it being slightly too small, very similar hand size as well (less wide by .5cm). Vaxee E1 is a really good fit for me. essentially the same shape yet sized up by a slight amount, most noticeably in the back where my hand sits quite a bit higher. for a significantly more supportive mouse, pulsar zywoo might be a good fit.
> Vaxee E1 > Pulsar ZywOo edition Absolutely cannot go wrong with either of these, Budapest Major 2025 and IEM Kraków 2026 winning mice right here. The only other ergo you're missing is the EC2-DW Glossy White (flameZ).
> Weight means very little in competitive gaming. Price doesn't matter if the product is right for you. It's funny, weight for me is more important in my competitive gaming career nowadays and it's hard for me to go back to anything over 50g. But you're right though, if product is right then price is no object. I went from Zowie to Vaxee to FM to finally settling on the Pulsar X2 CL. That's over $600 spent on just four mice (if we're talking specifics, I spent way more than that on more than four mice). I'm even willing to spend more if Zowie ever goes the Pulsar route and begin venturing onto lightweight mice. In fact, I'll buy them in a heartbeat despite being over $150. Same goes for Vaxee, they are both fantastic companies.
I also get knuckle joint pain from so many years of clicking and also my job that strains my hands a bit. Some mice make it so much worse. The new haptic clicks on the logitech g pro x2 superstrike have felt very nice to me so far with no pain. You can adjust actuation point and how strong/soft the click feels. If you set the haptic level to 1 with a low actuation point, you get extremely light clicks that feel nice. If you dont wanna go that route, vaxee mice have very light clicks on most of their mice. The vaxee E1 is ergonomic if you want an ergo shape and has very light clicks.
if you like symetrical mice with a bit of a back hump, you want flatter sides, such as the superlight (or clones), Pulsar x2 crazylight, VXE R1 or Mad R Major. you can even try out the Zowie S2 or ZA13/Lamzu Inca. if you want a symetrical mouse with a flatter back hump or low profile, you could go zowie fk2(although the sides aren't flat), Beast X(usually claw grip but i believe its doable), Lamzu Maya/Maya X. Maybe even the Viper v3 pro could work but i wouldn't recommend it imo shape and price wise. If you want to try out ergos, you can go for pulsar's xlite series, Zowie Ec2 or 3 (make sure its either -C, -CW, or -DW), Razer Deathadder v3 Hyperspeed(mini) Vaxee's E1, or WLmouse Sword X.
VAXEE or Zowie, known for their perfect build quality. If you like the shape of your prime, look at VAXEE E1 or Zowie EC2-DW
If you want same shape, low weight and better click latency, look at Pulsar xlite crazylight medium. If you want the zowie experience but with lower latency, 60 g and a very slightly smaller and different shape, look at the vaxee E1
