I just bought a new browning bow and I' ve been shooting alot lately and I don' t have any vibration that I notice and the only sound I hear is the twang of the string (I don' t have the string silencers on yet.) Do I really need a stabilizer then or do they do more then take care of noise and vibrations?

But I only have it set to 47 pounds do to a shoulder injury. will I possibly need it when I turn up the pounds?
