I recently came into contact with the creator of RB sticks. I'm not sure how far reaching this brand is, but for those who dont know, these are rotationally balance sticks, with set in weights that make the balance points of a pair of sticks not even 1/10 of an inch away from each other. Amazing stuff. I wanted to know if anyone else has had experience with these sticks, how they have held up over a season of marching and such.
