The basic construction of STRATO is based on that of our classic carbon blades such as SPEED OFF++ and POWER OFF+. But, replacement of older carbon with newly developed ENERGY CARBON realised another level of performance and feel. Improved efficiency of energy due to the lower damping of new material makes more powerful strokes. Further it gives improved control. KISO HINOKI of improved quality is used as top layers, and provides very comfortable and mild feel. This improvement gives STRATO the ability of all-round play though it is very fast blade. Topspin is more stable than players expect, and draws very sharp trajectory with good control. If a player can become accustom to the high speed, he/she will be able to perform every technique with ease.
