Hi, I just had a question on replacing the original grip that comes with a racquet (not an overgrip). How much overlap is there? Looking at the back of the replacement grip with adhesive facing towards me, there is a centre cotton strip (for lack of a better descriptor), and the rubber backing extends beyond the width of the cotton strip, like wings. Do you overlap just the wings? Or do you overlap the cotton backing as well? How do you finish at the top? Just cut on an angle and tape like an overgrip? Thanks.
