Also, too many rubbery joints could add too much flex to the system. That rubber also helps get some bite at the joint at the same time I bet, though.
It's not really rubber, it's vinyl dye. You can dip yours in the liquid rubber used for tool handles. That would give it more grip and a little more vibration control.
