shinso what's your opinion on the XM1
I have been using it for the past month (I upgraded to it from a poorly chosen g603 wireless that hurt my wrist). Even tho the mouse feels maybe a bit small in my hand (I have 20cm in length and 10-11cm in width), I can grip it pretty well with claw grip (even when my hand sweats).
The feet really glide (I have a cloth pad), the cord is light and flexible (of course it's not the same as wireless, but with a bungee/or at least if the cord doesn't slide of the table you should be good to go - I use some makeshift bungees on the back of my monitor so the cable doesn't go off my table). Something similar to these ones
As a final point, the weight - moving from a 99g (I used a AAA battery and tin foil to reduce the weight as much as possible) g603 to a 70g mouse, it really felt a lot better in game. I would suggest to go for a lightweight mouse.
PS: The g305 with one AAA lithium battery and some tin foil/battery adapter would get to around 83g (the AAA battery should be around 8g compared to a duracell standard AA battery which is 24g). So, if 83-85g is lightweight enough to you, it could be a better option, since wireless imo provides a better feeling.
