My latest mouse is Optical.
I'm not overly fussed what the tracking method is as long as it produces good results. The optical in the Deathadder 2013 is considered to be very good, hence why I went for it. If it offered the same performance in laser, so be it! 1800DPI, standard out of the box windows sens. Would probably consider myself to be quite low sens, not hugely but probably much closer to low than high!
