I posted a thread about the Valkeen whistle a while few days ago and it made me wonder what whistles are commonly used or any people enjoy using. Personally I have only ever used the Fox 40 Classic and was wondering if any people prefer other brands such as molten or Acme?

Hello. I just registered to this forum. My name is Victor and I am a referee in Sweden. I have uploaded a video to YouTube with famous FIFA whistles and some less famous whistles where I show how they sound from different distances and with different variations. If you want to see it...
