question 1: neither, really. optical works better in every aspect currently, unless really high DPI.
question 2: not laser
question 3: anything with really low friction should be good. I have yet to find one that offers better minimal movement than the fUnc F10s/F30r. but the control is really low. takes a while to get used to.
but comfort might be key here, a large cloth pad could be a lot more comfortable. for precision cloth, the Artisan HIEN MID is a true winner for me. very good precision and control, just not the fastest of their lineup.
another BUT: the G400s feet are not great for cloth pads. the small foot on the side just scratches against cloth pads in a very uncomfortable way when you rest your hands weight on it
though, with 3200dpi, you're bound to have a few precision issues.
for a new mouse and pad setup, I would recommend: Mionix Naos 7000 and the Artisan HIEN (mid or soft, depending on comfort level you want. indicates thickness of pad. thicker = more comfortable on the wrist). ergonomy is top notch on this combination, precision should be really high, and likely works better on higher DPI than the G400s. you could try setting it to around 2000 and see if you can get used to that.
comfort and ergonomics is very very important when choosing a setup - I believe everyone here on geekhack sits by the computer for a long time every day
Thanks! Yeah, I really need to watch my ergonomics. All is good now, but I want to keep it like that. Started using mech keyboards 2 years ago.
Did you hesitate between the Naos 7000 or the Avior 7000? I notice that I switch between palm grip and claw grip and I am not sure whether I could 'palm a little' on the avior or 'claw a little' on the Naos. Usually, I start out in palm grip. But when stuff gets intense (e.g., fragging in a fps or close pixel work), I find myself moving towards a claw grip.
And why that Artisan? Is it silky smooth? Why that one particular (just curious, learning a bunch new stuff)
I actually don't use the Avior or the Naos, but I would've gotten the Naos if I was a palm grip user. I actually use fingers only to control my mouse, and I use a Zowie FK for that.
the Avior is a bit awkward for me personally, but it's a great performer if you like the grip.
I know how that is
been trying to get used to palm grip for ergonomics but it just isn't working for me. I actually realized my hands hurt more from that due to clenching differently. with finger grip I am a lot more relaxed, and actually play better. well, I understand your concerns - I don't think the Naos is very claw friendly, unfortunately.
as for why the Artisan: the Hien is not silky smooth, it is actually a bumpy surface, and with large mouse feet, it glides really well. you get very good minimal movement precision and moving/stopping control. I don't really know why or how that works, but I've tried almost all the Artisan now and it's IMO the best precision/control pad they offer. plus it gets smoother with time, which feels nicer.
if you want something close in performance, but silky smooth, the Hayate is super good too. but it feels a bit more "sticky", meaning less minimal pixel precise movements. but it is still really good. just not AS good.
and for the Kone XTD Optical - the sensor is the same as the Deathadder 2013. if the firmware is any different, I can't say. but the DA2013 has a slight problem which is a lot of smoothing, that causes input lag, but makes for a smoother mouse movement feel. I personally think it feels a bit less responsive and a bit too "smoothed". still, it isn't bad, just that there are better options.
the Kone Pure Military uses the 3310, and is suited for claw/palm grip for medium/smaller hands though. I do like the shape, and it is somewhat reminiscent of the G400s, but a little bit smaller. tech-wise, it's one of the best ones out there it seems.
