I have both, and carefully measured the weights, and the opposite is true:Vic Firth, 2.8ozPromark, 2.9ozAnyhow, I personally like the Vic Firth because they have a really good grip, that is, they don't slide when holding them.

Very good feel as far as gripping the stick

What's important is that these sticks have a nice grip, a nice balanced weight, and they don't break often, as long as you play daintily, which I do
