Hello, I tried a Butterfly Power 7. What a blade! Of course like all good things in tabletennis it's been discontinued. Now I'm looking for a koto-ayous-ayous-ayous-ayous-ayous-koto that ideally should be close to 5.7 mm. I found DHS Power-G9 (6.3mm) and YinHe Uranus U-2 (6 mm). Anyone that can directly compare these blades? Do you know of anything close to Butterfly Power 7? Thanks.
