The IME 3.0 is definitely my favourite stock mouse of those I've tried (WMO, IME 3.0, IMO 1.1, MX518, Logi WMO, A4tech X7). I played with a friend's Deathadder but the slippery sides really annoyed me. It feels REALLY heavy even though it isn't.
I've put some thought into what makes the IME feel so stable in my hand (claw grip). I've realized that a key for me is the mouse ass should only touch my palm at the base of the thumb and it should stay there. This stops you from losing the ass of the mouse. The grippy surface of the 3.0 is perfect for this. Also the right of the mouse should have a relax spot for the ring/pinky fingers that slopes down slightly, but so the pinky can still touch the mousepad for stability/awareness.
I could weight mod my 3.0 but I can't bring myself to do it without a backup, so instead I'm trying to get these features onto my WMO with sugru. I've already stripped the cable to the 4 USB wires only so that isn't an issue anymore.
The next mod that I want to do is better mouse button hinges. They deserve to feel better and that shouldn't be hard to achieve. I want to have the ability to tune the force do my liking. The index finger should be doing a lot of aiming but if the switch is too light it can't direct the mouse without firing a button.
As for the switches, the last Omron D2...s that I test are 75 g as you would expect, so I don't know what is going on with the switches in the Logi WMO that are definitely 50 g. Strange.
Btw, I have a semi-objective way to judge my aiming ability with different mice/mods. I do this reflex test a bunch of times, with the page Ctrl+ to maximum size.
