Recently bought a new rod. I left the original plastic wrap on the handle cork. I then wrapped a tennis racquet grip over the original factory clear plastic and wrapped "high pressure / high temperature" electrical tape over the ends.

It gives me a slightly larger grip and the rubbery material is easier to hold than the cork. Now the tennis pro fellow at the tennis shop is still wondering about where one gets a "5 weight" after he asked what I swung around for a racquet......
