Donnay spent a huge amount of time, money, and massive amount of advertising for their X and X dual series racquets. Now they are no where to be found. What specifically happened that made them disappear so fast? I think even Jim Courier even used them in the "Senior Series"( whatever name they change it to from year to year) events. Just sort of odd to come and go so fast with such a decent past history of decent racquets.
