U2 V2 Mini

Mchose L7 pro ATK dragon fly A9 series Zaophin Z1 pro DeluxM800 ATK Blazing Sky U2 Mini Superlight Try this it's a mix budget that is close to a mini viper shape they are all wireless and some is budget but high end Quality

Ring finger and pinky are together, which is a relaxed grip more common in palm grippers. Fingers are fully extended. Like rocketjumpninja. Only not relaxed thing is your bent thumb angle. U2 has a nice thumb groove that might feel nice. Atk u2 is basically a clone. Check it out on eloshapes. Valkyrie vk m3 and atk u2 mini are smaller "U3" size options.

That's a fingertip mouse, but the Darmoshark M3 Micro is like a full sized mouse just shrunken down and fairly light at less than 45 g but if you battery mod it it'll get a lot lighter because the stock battery is really heavy. Honestly for a cheaper option I would say the ATK U2 Mini is a good option at 40 g as I like the normal sized version with my 18.7 cm x 9.8 cm hands.

You probably need a smaller mice if you claw/palm the g304 a bit and liked it. I say you maybe have somewhat a smaller to medium sized hand(17 cm is my guess), but I would say probably also look at the mchose L7 ultra plus or the ATk U2 V2 mini might also suit your style. The R1 pro is also a okay choice but i would say L7 ultra plus is the better higher quality choice. If you are also interested in pink coloured mice also look at the Maya as well, they are a bit expensive but it is truly an impeccable mice (I own the Maya X currently, which is the enlarged version of it). The Rapoo VT3s max also have a very interesting yellow colour and is a good choice if you're interested in small to medium sized ergonomic mice as well.

Atk f1 v2 with new mcu - viper mini shape clone - it would be so good for your handsize or Atk u2 v2 mini for more locked in feeling claw grip.  For more budget options take a look on Rapoo vt1 original shape but similar to lamzu maya Rapoo vt0 ninjutso sora clone. U can buy rapoo with free shipping from 35$ with code for 20% discount. All of these have new nordic mcu with superior battery life. I just recommend mices with new mcu cause its just better.
