I think this should only be for Demo. The pompom on the end being a sticky fits nicely and the other classes just having a ball one really doesn't look as nice.

it would be a lot better if it was just for 1 specific class and not all class

I really love the goggles.

I like it.

Reminds me of Macho Man.

Because the only difference between the regular pom pom and the "sticky pom pom" is the addition of a few spikes. Its not a different color or drastically different shape.

Its an aesthetic choice best kept under control, instead of going wild with it and just putting whatever on the hat and potentially ruining the feel of a hat by over-doing a small joke.

How come Demo gets a sticky bomb instead of a pompon on his and everyone else gets a pompom?
While I try not to sound whiny, I was thinking Scout's would be a white pompom with baseball stitching.
Pyro could get a little Balloonicorn head on theirs.
Tiny Jarate hanging off Sniper's hat'll keep anyone from stealing it.
