Xiom Hayabusa ZXi

My Coach in Korea used this one on a daily basis, so you can understand its durability, she gives lessons non-stop 10-12 hrs a day.

ZXi is a spin machine for loops that packs both a punch and control of where you put the ball if you pair it with the right rubber, like Sigma II Euro or a similar softish modern rubber. You got about everything you can ask for: Spin in bucket loads, control, good feel, no crazy earthquake vibrations, and a feeling that you are a Korean ace. Blade is medium feel, moderate vibration, and low to medium OFF range on powerloops. Blocks like crazy if you can take it off the bounce. Coach will block you off the table using this blade.
