@wbrowar They are balanced differently, more heavy to the back, which makes them rebound stronger. Some people say they can play faster and more accentuated. They feel really different, but I'm not yet sure if I like them or not...
@_cirrus_ To me rather a marketing gag - like so many "new" products in music industry. You have sticks with all kinds of balance (i.e. weight and diameter distribution between tip and grip) already. And as to Pro Mark's durability claim: From my experience Rohema's hickory sticks are the most robust sticks I ever played.
