I will be buying one of these rackets! The question is what's the difference between them apart from the paint work and one it a little older! OK the x London has "Hybrid Composite" and the JJS has "MaganGraphen" but I think they are the one and the same just in the case of the x London the did not call it MaganGraphen! A new paint job and marketing for the last racket for JJS and there you have it! OK the thing is in the UK the JJS is £125 and x London is £95! Is it worth the extra money for the JJS?????? Hope you can help Cheers
