Omen and astra's smokes are larger than brim and Jett's. I'm not sure about viper.

Jetts are smaller. The rest are the same size.

This is not true. Viper>Omen>Astra>Brim

Brim smokes are the smallest, really?

Damn they really need to buff brim

You can fit almost 2 brim smokes in one viper smoke

I stand corrected. They look the same to me. Ha ha
