Well Noblet,

I am under the impression that you really can't choose which ref you want for your match however I think that if you go up to the tournament director at any tournament throughout the year excluding qualifiers and national type tournament you could ask him to have a different ref during your match. Im not sure if it would be possible for him to be there every time your son wrestles and to make sure he is not ref'd by that particular one. But I think some accomidation could be in order. But hey that is something you would have to check on.
