My Personal Crosshair:
I have other crosshairs in the past and this seems to do the trick its big enough, move easy side to side and just all round a good crosshair (Heads up, this is Get_Right's from NIP Crosshair!)

cl_crosshairalpha "200";
cl_crosshaircolor "1";
cl_crosshaircolor_b "50";
cl_crosshaircolor_r "50";
cl_crosshaircolor_g "250";
cl_crosshairdot "0";
cl_crosshairgap "0";
cl_crosshairsize "5";
cl_crosshairstyle "4";
cl_crosshairusealpha "1";
cl_crosshairthickness "1.5";
cl_fixedcrosshairgap "0";
cl_crosshair_outline "0";
cl_crosshair_outline_draw "0";

This one's for people who enjoy rifle spray!
cl_crosshairalpha "255";
cl_crosshaircolor "5";
cl_crosshaircolor_b "255";
cl_crosshaircolor_r "255";
cl_crosshaircolor_g "0";
cl_crosshairdot "1";
cl_crosshairgap "2";
cl_crosshairsize "2";
cl_crosshairstyle "4";
cl_crosshairusealpha "1";

Heads up, this one is pretty much a dot and is for people who are skilled in aiming for the head!
cl_crosshairstyle 5;
cl_crosshaircolor 5;
cl_crosshaircolor_r 150;
cl_crosshaircolor_g 50;
cl_crosshaircolor_b 5;
cl_enablecrosshairalpha 1;
cl_crosshairalpha 255;
cl_crosshairdot 0;
cl_crosshairsize 2;
cl_crosshairthickness 0.50;
cl_crosshairgap -2;

This one is similar to the one before smaller dot though.
cl_crosshairstyle 5;
cl_crosshaircolor 5;
cl_crosshaircolor_r 250;
cl_crosshaircolor_g 50;
cl_crosshaircolor_b 255;

cl_crosshairalpha 255;
cl_crosshairdot 2;
cl_crosshairsize 0;
cl_crosshairthickness 0.75;
cl_crosshairgap -1;

This one is a next to nothing dot, and if you use this I strongly recommended aim for the head.
cl_crosshairstyle 5;
cl_crosshaircolor 5;
cl_crosshaircolor_r 250;
cl_crosshaircolor_g 50;

cl_crosshairalpha 255;
cl_crosshairdot 1;
cl_crosshairsize -30;
cl_crosshairthickness 1.50;
cl_crosshairgape -1

I recommended this one for ak and m4 users.
cl_crosshairalpha "255";
cl_crosshaircolor "1";

cl_crosshairusealpha "1";
cl_crosshairthickness "1";
cl_fixedcrosshairgap "-1";
cl_crosshair_outline "0";

Like some of them this is for the 1 tap pro's.

cl_crosshairusealpha "1";
cl_crosshairthickness "1";
cl_fixedcrosshairgap "-1";
cl_crosshair_outline "0";
cl_crosshair_outline_draw "0";

I recommended this one for people that are new to game and want to see where there bullets will land.
cl_crosshairalpha "200";
cl_crosshaircolor "1";
cl_crosshaircolor_b "50";
cl_crosshaircolor_r "50";

cl_crosshairusealpha "1";
cl_crosshairthickness "1";
cl_fixedcrosshairgap "-1";
cl_crosshair_outline "0";
cl_crosshair_outline_draw "0";

Even harder 1 tap pro's crosshair.

cl_crosshairalpha "255";
cl_crosshaircolor "5";
cl_crosshaircolor_b "255";
cl_crosshaircolor_r "255";
cl_crosshaircolor_g "0";
cl_crosshairdot "1";
cl_crosshairgap "-15";
cl_crosshairsize "3";

cl_crosshairusealpha "1";
cl_crosshairthickness "1";
cl_fixedcrosshairgap "-15";
cl_crosshair_outline "0";
cl_crosshair_outline_draw "0";

Last but not least, colours I recommended a darker colour and I enjoy using red so here you are.

cl_crosshaircolor_b "255"
cl_crosshaircolor_r "150"
cl_crosshaircolor_g "50"
