hello guys and gals. I have a badminton racket that I used many years ago (when I was 16) now 25 years old. anyway, I recently started playing again with my girlfriend but noticed my racket needs re-gripping. I purchased the karakal pu grip online but have seen in all the online guides that once you have re gripped you must put some sort of tape around the top to stop the grip coming off. what is this tape and where can i buy some? many thanks, mat-nick
