So I'm considering selling my anger because every last sniper in tf2 has one, and I don't want to look like everyone else...I thought about buying a cold killer, but then I realized I want a hat that helps me. So, any hats that make you harder to shoot, or that at least don't put a big target on your head? (not including unusuals)
The other larger hats may throw off some noob snipers, but I prefer to minimize my visual profile to avoid being seen as much as possible. Sometimes large hats can be seen over a fence or other obstruction when the sniper would normally remain unseen. The snipers nest area in hightower, for instance, has a fence leading up to the stairs that would allow a large hat to be visible behind.
Sniper battles are ideally won by attacking from an unexpected direction.
If you want to be an anti-sniper, you could consider using the Croc-o-Style Kit. Equipping the ol' snaggletooth hat along with the sydney sleeper, danger shield, and bushwacka, makes it so you cannot be killed by headshots. Out of any hats out there, this one by far gives you the most "utility".
It also looks awesome as a set.
