While it may sound counter intuitive, dangling a weight from the tripod is not
the best solution.
A mount system works best when it has high stiffness and low weight. These two things give the system a higher natural vibration frequency, which dampen out far more quickly than low frequency systems.
You'd do better by replacing a low stiffness component rather than adding mass to the system. (This is also why the three bolt "rat cage" you see as a levelling system to an EQ mount are really bad ideas).
Have a read of Roth's Compendium of Practical Astronomy (Vol1) if you'd like to know more about this
