Beast x, xtrfy m4, logitech g pro superlight, the new version of the razer viper, g wolves htx ace, lamzu maya x, logitech g502. Out of all of these the superlight/maya would be my runner ups but they dont even come close.
endgame gear xm2/op1w4k, lamzu atlantis/maya, ninjitsu sora, vxe r1 pro, scyrox v8, hitscan hyperlight pulsarx2, gwolves htx ace. All have 0 ms debounce software + under 60 grams wieght
Gwolves htx, Hts, Hts plus are all small lightweight wireless mice. I main the htx ace, its the only small mouse under 40g with 6 programmable buttons. Have also heard good things about the Wlmouse Beast Miao if you want something even smaller and cuter.
I've been holding my htx ace exactly how you describe holding your g305
ATK VXE R1, Mchose L7 Pro (smaller hands / X2 shape), Mchose L7 Ultra Plus (larger hands / Sora V2 shape). Those are the best budget mice I can think of. Another pick I like, personally, would be G-Wolves HTX Ace/HTX Ace 4K. That's a pretty solid budget entry from G-Wolves, can find them cheap time to time.
Ulx small, htx ultra, htx mini Try them, I have small hands and I love them.
