if mouse turns on and off its simply a broken cable.

Skull is right, if the mouse turns off while moving it, thats is the damaged cable and fixing it is a easy go :}

But since i got an impression u want a new toy, and now u have confirmed that, here we go;

With the sensitivity u have described u need mice that have at least 1600CPI, first what comes to my mind is adns-3080 witch is used in mices like mx518, Kova, Naos 3200 there are also a4tech models x748 and x738 i do not advice them because in my opinion they are big and uncomfortable also the wierd CPI managment cause in them negative acceleration thought on Yours fast sensitivity u wouldn't notice that anyway.

ADNS-3080 is quite fast sensor and the only flaws of this sensor is probably the axis snapping prediction witch is quite heavy on it.

mx518 rev1 with ADNS-3080 and rev2 with ADNS-3080E, the mouse is definitely for palm grip, there is no place for two fingers on right profile witch might made the mouse a little not comfortable holing it that way, by holding the mouse by only one finger on right improves comfort.

Kova, haven't used myself so i can't talk about shape

Naos 3200, haven't used it, but well the mouse seems to have profiled shape for two finger on right side witch would actually made from it a primary choice if u do holding mice that way, but keep in mind this will limit wrist movement and the mouse going to be total palm grip.

If u want to have mice without prediction u need to look for adns-3888 (IR 3.5 Abyssus, Dethadder 3.5G) sensor and adns-9500 (a lot of mices XAI, M8000X, G9x, G500, Naos 5000, Qpad 5k there also are few others but i do not remember exact names right now).

adns-3888 is Infra Red sensor the last generation of LED sensors witch gives up to 3500CPI, mouses with that sensors behaves familiar to previous generation of the sensor adns-3668 used in Yours DB 3G and DA 3G. adns-3888 haves outstanding top speed, but it also have one flaw, the pointer seems to jitter on some surfaces with the highest settings it is most noticeable, but if u going to set the cpi to 3500 and reduce driver sensitivity to 5 u should eliminate that effect to almost a 0. I am currently using Abyssus and playing at 3500CPI believe me there is no jirtering in game and the mouse preforms outstanding.

DA 3.5G well its a rather palm/claw grip, for slower playing and aimers it limits wrist movement a little. Right profile of that mouse seems to be uncomfortable if u having 2 fingers on its right side if u are placing one on finger on right side the comfort improves a lot.

Abyssus thats a really small mice for fingertip or claw on smaller hands, the good thing is Yours wrist on it have full range of movement and then the in game movement is easier than on DA or any ergonomic mice around. Thought the right side profile is far better on that mice than on DA then placing only one finger on the right side makes it more comfortable.

the second option adns-9500 is a Laser Sensor that allows 5040CPI, i haven't used any mice with that sensor, but on internet people often complain about this sensor, that it is to sensitive for dust, and have positive and negative acceleration on some higher speed about witch u shouldn't really worry about since u do use quite fast sensitivity. Nagi lately have bought M8000X and he seems to be really happy with that buy, he do playing at around 20cm/turn u can talk with him about that mice. Consider also the wrist movement if u choosing a shape if u want more comfort or more free movement.

Lots of shapes that i haven't tested out, but they seems to be better for two fingers on right side than DA or mx518
