I've modified an anti-vibration mount from a P1 to fit my P2. The problem is, the balls are not isolating the vibration and GoPro 3 is shaking (not vibrating so much as actually shaking) and it'll get so bad that it actually affects the craft. My question is, aren't the balls different stiffness? Are they colored coded? I thought I read this somewhere here but now can't find it.
