Coming from the DHS PG7 all wood blade, the Yinhe Y13 felt very different from what I was used to. Y13 felt very solid with minimal vibrations compared to PG7. While the PG7 offered better "ball feel", it was slower than the Yinhe Y13. The fiberglass layers right underneath the outer limba ply helps stiffen the blade. The result is a fast OFF+ blade with exceptional speed while maintaining control, and for my game, the right amount of stiffness/hardness. Both the Yinhe Y13 and DHS PG7 were great for blocking close to the table. However, looping from far away is really where the Yinhe Y13 surpasses the PG7. The Y13 had the extra "oomph" to generate topspin while not sacrificing power during far table loops. Meanwhile, the PG7 was great for looping but lacked power from mid-far table play. Overall, the Y13 has a shorter dwell time and is faster than the PG7. It is a perfect blade for those who want to transition from an all wood blade to a composite blade.
it is said to contain two fiberglass layers. Thickness is as expected 5.7-5.8 mm, weighs 90 g. Ballance is slightly head-heavy because of the relatively larger head - 159x151. Construction of the blade seems to be limba-GF-ayous-ayous-ayous-GF-limba.
