It is extremely difficult to find a vane that offers just the right amount of steering while minimizing drag.and overall weight. Other brands offered reduced height and weight, but I experienced arrow flutter at the longer distances. The X-2 provides just the right amount of steering while reducing weight. This allows for a greater percentage of FOC to further aid steering, a win/win!
These vanes are tough too! During the Redding Trail Shoot last year I had a number of pass throughs , yet the X-2 vanes came through unscathed!
