Whilst Murray was playing yesterday, I noticed that it appears that he isn't using a standard iradical as the PJ suggests. He has the CAP grommet commonly found in the iprestige. Isn't it a bit odd that his PJ is of an older racket. It makes more sense for him to use the prestige as it is a heavier frame. Also, why do the top Head pros have a black buttcap with a silver Head logo when the stock models are always different. Is it purely for advertising or is it a special 'perk' of being a pro? I needed to replace one of mine not so long ago so phoned Head and asked for one of thsoe and was told they aren't available to buy.
