Hi share your Crosshair if you like to here is mine and why am using this type. I prefer the small red square to be used because it will help you more to get someone headshot especially when he hiding behind a window and only his head showing .
I recently changed mine when I got back in css, i had a crosshair just like vandiver's for years until recently I decided to go for a normal one similar to Jan's, reason being the center dot crosshair used to cover the enemy head when in distance, where as now I get the head in the middle of the crosshair..
