hmm, well i been using my DA for about a year now, until one click, it goes double click, thanks to me playing godfather 2 (EA), where the shooting mechanics just makes me spam the clicks too much, and "ka-blam!" ohhh shit! i need a new mouse now.... so far i can tell, the smoothness uh... depends on what mousepad you use, i tired it on my exact mat seem okie (hard though, thats a nature of tat hard material mousepad), but on my friend's "SteelSeries QCK+ Fnatic Edition" seem good, since its soft and treats your mouse like, your writing it on paper, not wood (i might get that! hehe! but now cant, pokai adi >.<)

Since im used to DA with mah "hands" (refer to picture that moderno took) i used the "claw" grip to control my mouse around, and now with the mamba, its better to handle... and much comfortable, since the mamba has rubber pad at both side of the mouse and when you "hold" it with ur fingers its damn comforting, thus the mamba is actually makes it want you to "move" it around more with confidence. That's where the dpi and the technology comes in to play and the wireless makes your hand and mouse free together to do want nonsense play style you wanna do with your mouse, you might treat it like a bike and "make your moves" with it like those X-games fellas im really saying what i think i could say about it, with the different point of view to say about the mamba, and i might be different to other people whose using it or not

to me now the mamba is like an upgrade to the DA, i dont know about the diamondback fans, the lachesis fans and salmosa users (freaking-ly small mouse), i think they might need sumtime to get used to it

If you read this far, it sound like im giving a short review, and i think i am, thanks to sum reviews i read thoughly, and not that serious during the hours i was thinking about getting the mamba lol hope you'll understand what im trying to say:P heh >.<
