Trying to recap my pro tour 630 since i thought it needed new grommets. However the xt prestige grommets that are the only available black ones here in europe anyways seem to have a very poor fit. My stringer just called me and told me he couldnt get it to work, the string broke the grommet because of the poor fit. It was relly hard trying to put them on by the way, even though i used a hairdryer i still couldnt get it thru the last holes on top but i figured when he would string the raquet he might be able to but didnt work. So i see the graphene prestige grommets are still around(red ones) anyone have any experiense with those? From all the grommets ive used the transparent IG ones where the easiest ones to put on the raquet, never tried the red ones though....
