AimIsADickFor the dragon's fury, I use a light green hollow square that has a red hollow square in the lower right. The red square is supposed to approximate where the centrepunch hitbox would be relative to the centre of the crosshair, and it does a pretty good job of that. Thanks to this crosshair I've been able to improve my DF aim a bit and hit centrepunches more consistently.
For the Gas Passer, Jarate, Mad Milk, and Huntsmans, I have a pretty bad rendition of an artillery crosshair. They really need improvement, but I'm not sure where else to go with them, aside from [strike]ab[/strike]using material proxies.
Other weapons use a green circle.
