This beater series by Vic Firth is absolutely spot on. I use either the wood and felt versions almost exclusively now (over stock beaters), depending on the sound I'm after. The shape of the beaters is great - striking the drum with the rounded edge gives a very consistent sound and using the flat face gives considerably more "oomph"! They're also very solid and I can't imagine anything going wrong with them. I don't go anywhere without having both options in my stick bag now!
The wood one, VKB2, caught me by surprise - I don't usually like wooden beaters, but this one is a great weight and the sound isn't over the top. I use it when I want more definition - usually when I'm not miced up and the felt can be a little too muffled. In fact, the first time I used the VKB2 over the VKB1, a friend of mine commented on how he liked the more "woody" sound my bass drum had that day - he couldn't believe it when I told him it was my first time trying a wooden beater! The man has magical ears!! Great beater. Get it!
