lol guys i use a cross hair size of 4 a little blue dot

Geez I use the biggest crosshair of you all.... size 14. Might try a smaller one some time.

Super,

Try royal blue, it stands-out pretty well.  I also use the dot too, with the default size.  The dot turns red when I hover over my teammates.

I use neon green normally and have the crosshair turn off when over a teammate...figure its harder to TK if I don't have some thing to aim with. ;)

I use a x-hair size of 10 with a rez of 1280x1024, so I can still see guys at a distance.

Well I'm off the dot and onto that big circle with the cross through the middle, coloured solid red. That way I never loose my crosshair :P I actually set it up that way for a friend to have a game (he couldnt see the dot enough), and played with it after and quite liked it

I use a size 9 crosshair with a 1024x768 resolution. i have it white atm but i frequently lose it when a smoke nade is used and against some of the backgrounds, i tried yellow once but i lost it on jor1 alot. i may try that pink one as it sounds good

I use cg_crosshairRGBA 0,1,1,1 it's kinda of this aqua color. So unless you are planning to take a swim it doesn't blend into the surounding. I've tried yellow, white, red, purple, green.. with different ? too (where ? = x,x,x,?)
But up till now 0,1,1,1 is the one I like best. and about size.. mine is at 18 atm. with 1280x1024 resolution. had it at 10 But since I stare at a monitor the whole day at work my eyes are kinda tired when I get home to sof.

0,1,1,1 is not aqua like but I think Cyan??!!
