A lighter weight means improved handling characteristics. A moderate width sleeve, 7 battens, and 3 cams provide draft stability through a huge wind range. Combined with a higher aspect ratio, the OverDrive M4 has impeccable handling characteristics; a lightweight feel, with a softer flex. Smaller sizes (5.5 and down) have 6 battens to increase flex and control for when conditions get extreme.
