I've been trying out different mice for the last few years, but haven't really been happy with any of them though, so I thought I might ask for "professional" help this time...
I have very small hands (barely 18 cm, see picture), so I use the palm grip most of the time.
Grip-wise the Logitech Anywhere MX (see picture) would probably be the best mouse for me, but the movements of that mouse are way to jagged in games. (I guess the polling rate is way too low, so as to preserve battery life?).
Also, I'm a high-senser (I usually configure mice somewhere around 3600 CPI/DPI, if they offer the option), since, in addition to my hands, my arms aren't very long either, and I can't really do those >30cm swings comfortably (or I'm maybe just too lazy). I usually play with something like 5cm/360°, but I still end up lifting the mouse up to reposition it, when turning the same way multiple times in FPSes.. Which is another issue with heavy mice like the Anywhere MX (it has 2xAA batteries inside) - this is the reason why I usually prefer wired mice (though I don't mind wireless ones, if the batteries last for at least a week or so)
Other than the Anywhere MX I've had the Kone+, the G600 and the Razer Ouroboros recently (in the last 2-3 years). The G600 actually fits somewhat nicely in my hand (with all those grooves it has), but it is way too wide to comfortably pick up or to accurately move .. and the sensor has that nasty bug that it jumps halfway across the screen on some rare occasions. The Kone+ was semi-ok size-wise, but the left button died on me about 7 months after the purchase (issued a double click every few clicks), and both Roccat as well as the retailer refused to exchange the mouse for a new one, so I'm not too keen on buying from either of them again if possible. The Ouroboros on the other hand was a complete disappointment - first it was way too large (though that's probably my fault for looking just at the pictures instead of the specs), the thumb-buttons and the wheel-button behave miserably (if you push them half-way through they make a "click" sound and feel like having clicked, but don't actually issue a click - you have to push them in further for that to happen). Additionally the Feet/Glides/Skates on the Ouroboros are probably the most ineffective ones I've seen on a gaming mouse so far..
So looking at what other mice there are out there, I noticed that the Razer Orochi seems to be the only other "Anywhere MX-sized" mouse with gaming-ambitions with more than one side-button (other small mice like the Roccat Pyra, Zowie Mico, SteelSeries Kinzu/Kana all have less than two side-buttons, right?) ... but it has that dreaded Phillips/Twin-Eye sensor and is probably too heavy given the batteries.
Looking at "full sized" mice, the Zowie AM/FK and the Steelseries Sensei Raw (the Raw because I imagine the metal of the Sensei to be quite uncomfortable) caught my attention, due to being slightly smaller than the rest, but still gaming-grade mice. Currently I lean more towards the FK, given its low weight and width .. but I'm unsure about the sensor. I've had "predicting" laser mice ever since they came out with the Logitech MX1000 back in 2003 or so. How much of a difference (or effort to re-train yourself) is this really?
Then along with the mouse, I'm also looking to change my mousepad. I've had the Roccat Sense for the last 3 or so years .. but it's way too large, so I end up putting all kinds of stuff on it, and as a result it's fairly dirty by now - though it does not appear to be worn-out as far as I can tell. Originally I was planning to get another one just like it (with that smooth/tight surface), but then I read in your mousepad guide that those pads consume the feet/skates more strongly than rougher pads like the QcK. How large is the difference really? How often do you end up changing mousepads and mouse-feet/skates?
The only other question (from the first page) left unanswered so far is about the price. I'm not really sure how to answer this, as there's no real constraint on the budget and I'm comfortable with €100+ mice .. though I probably still won't be spending some €60+shipping+customs on japanese mousepads...Edited by MontyB - 8/12/13 at 7:36pm
