I still prefer the default cross hair with dynamics turned off.
Those dynamics are a bunch of hooey, I used to suck (more
) when I had those on. I'd wait for the lines to move in, and BAM, dead. I turned them off, and all of a sudden, I'm killing people. I just assume they're solid when I stop - because they usually are. I've tried the dots before and wasn't much of a fan, though that might be from playing with the cross for so long.
I once made a crosshair sprite for the sniper rifle that didn't show the black at all and showed a normal crosshair in the middle. Unfortunately, it was hard as hell to make a shot with it. And it got me banned from a server or two in a matter of two days. I just stick with my good ol' hacks now
