Working in collaboration with some of Vater's big-name, up and coming endorsing artists, Vater has come up with a new series of sticks that will fill a big gap in the drumstick market. The new Xtreme Design Series models, XD-5A, XD-5B and XD-Rock, have been designed and manufactured to meet the great demand of drummers who have been asking for stick models in between the very popular Vater Power 5A/Power 5B models and the Rock model.
