Does anyone know of a good place for restringing rackets in London? I tried a local chain sports store in SE London and they have a very limited selection of strings as part of their stringing service. This was also the case when I asked at Lilywhites in Central London. I'm looking to restring a racket with either Yonex BG80 or BG85. If the make of the racket will help determine the most suitable stringer, the racket to be strung is a 'Gosen' with an isometric shaped frame. Any recommendations or advice would be much appreciated. Thanks for looking.
