My advice: do NOT change anything

your setup is good and there is nothing you should change. if you see that the mousepad is worn off, then get a a new one. If you see that the mouse feet are worn off as well, change them. This will be way cheaper and way better for you.

Thank you very much for replying, belka.
Yes, This setup is very good for ql but i'm a little boring to use that mouse.
I have been using Ime3.0 for 3 years.
That mouse has no problem for QL. good.
but I want to use new mouse.

Anyway,
Your advice is good for me. Thx.

It is tough to resist the upgrade bug.

For the price, the mouse you are using is hard to beat. The abyssus for me is not a better choice than the IME 3.0. The abyssus depending upon which one you get may have jitter issues on certain pads... The IME 3.0 is very forgiving when it comes to surfaces.

If you absolutely have to upgrade your mouse I'd look at these options (in no particular order)

Zowie Evo EC1 or EC2
Logitech G400 (make sure to get one that no longer has prediction)
DeathAdder

The sensors in those three will at least perform close to the level of what you are currently using and I know myself that the G400 and DeathAdder are fairly forgiving as to which mousing surface you use.

From a surface perspective I like the following:

Artisan Hayate - (unfortunately expensive, you may not like the edges, since some feel they are "sharp", has less padding then a QCK Mass I believe, less friction than a QCK)
Puretrak Talent - (Less friction than a QCK)

I used the ime3.0 with qck+ and switched to abyssus and goliathus speed. I wanted a smaller mouse as I felt a bit clumsy for flick shots.

I heard reports of the abyssus jittering with the qck, although I never noticed it, using this combo for normal pc use.

puretrak talent or the stealth if you don't have the desk space

someone posted on overclock a code that i just used to buy a white talent... super good deal

"imma give you or anyone else an email code I got yesterday cause i dont need another one but use code: 23302ND3

its good on a talent or the white talent for like 35% off"
