Penn International VSX models are constructed to achieve the extreme drag ranges expected by anglers fishing with super-braids. Unlike other products that advertise their high-potential drag settings but fail to inform you that these drag settings result in drag curves that are anything but angler friendly, and have a high potential to pop lines, pull hooks, and result in lost fish, Penn VSX models have been engineered to achieve these extreme drag settings while maintaining an appropriate and smooth drag curve throughout the entire range of the drag-lever. Simply put, Penn Engineering at its finest.
