General
Promark has developed a unique way to keep your sticks from slipping out of your hands. The black ActiveGrip lacquer layer on this 7A model gets stickier as your hands heat up. The layer is just as thin as regular lacquer, so you don't have to worry about them affecting the weight or size of the sticks. You don't need to worry about them leaving marks on your drums or cymbals either, as ActiveGrip doesn't chip off. That means it'll stay off of your hands, too!
Rebound Balance
This pair of sticks has Rebound Balance weight distribution. That means that a relatively large portion of the weight is at the back end of the stick. In order to achieve this, the shoulder of the stick is longer than with a Forward Balance stick. The result is lighter playing and a stick that is more suited for playing with a lot of finesse and dexterity. The rather long teardrop tip makes it possible to get clear articulation and stick definition.
