I just went from a Copperhead to a Lachesis (Copperhead died and Lachesis was a gift).
So, from 2000 dpi to 4000 dpi, I can tell the lachesis is much more dead one accurate even at the same dpi settings I used for the copperhead, it just responds better.
So, I experimented, set polling to 1000 hz, DPI to 4000 and razer applet sens to 4, it responds exactly the same as with the default 1500 dpi and 8 sens settings. It's definitely much more precise and controllable than the copperhead.
