he Optimum PLUS is a five-ply blade that uses the same out- er plies as the best-selling STIGA Offensive Classic blade. It is faster than the Optimum SYNC, although the Optimum SYNC is a bit lighter. Thanks to Crystal Technology, the Optimum PLUS is much lighter than most blades of a similar speed. Crystal Technology is STIGA’s unique process that hardens the surface of the blade, thus increasing its speed. You’ll be amazed both by the crystalline appearance of blades treated with Crystal Technology and also by the extra zip on all your shots.
