I use to own a naga and deathadder chorma, both optical. However i use to set the poll to 1k for best precision in everything. I use a laser sensor now. For me laser feels better but it does not matter what you choose as long as it has high polling, the accuracy will always be good. Btw polling is how fast the info from mouse to computer gets sent. The higher thenpolling the faster movement with mouse is read.
