Yup, and Jimmy Arias mentioned during one of the Power Shares matches that Jim strings his frames at 73 lbs. Yikers. I see that he's switched from the Donnay X- Red 99 to the X Dual 102 Black recently. Wonder if he's always strung that high or if that has something to do with his transition to larger heads.
