I use a tiny bright purple dot, I used to used a white circle at the biggest size, and I'll just fire whenever they were in the circle. Not good for headshots. --- Only 10 More days till I'm an Icon. To celebrate, I'm going to make a shortcut on my desktop that doesn't go anywhere.
I prefer the default crosshairs. They seem to be pretty much the same as the weapon's Hitbox... The custom crosshair I used to use, a circle with a "+" through it, doesn't work on my prefered server. --- Not changing until a PyschoNauts 2 is released.

I did, for no-scoping as a sniper, but I just left it as is for all the other classes as well.
Once I heard the sniper rifle got it's own crosshair, I tried switching back. The original crosshairs are now just strange to me. So I still use the small circle crosshair. --- XBL Gamertag: ShadownetNinjaX
I use a small green dot as my default custom crosshair. It actually improves my soldier aim considerably because I can better judge now where the rocket will go exactly, so now when I'm firing just past a wall or ledge or something I can aim precisely so that it will just barely miss hitting the aforementioned wall or floor/ledge.
I like the "T" crosshair built into the game (no 2). I've always been a fan of the T in most games. The horizontal lines give me a reference to help consistency with projectiles that arc, and the vertical line helps with consistency when edging and lining up. I prefer it over the cross because a true cross obscures the center dot somewhat. No projectiles curve "up" so I find the top vertical line useless.
