Have tried this string on ISO 900 SR CN at ~26 lbs for 2 hours last night. A very powerful string but still found the string is a bit hard, without the soft feel like BG85/88Ti or Ashway MicroLegend. In general, this string is similar to Roots Aermet in terms of performance (it looks a bit more "oily"). p.s. Yonex Cyber Natural 100 is still not available in Japan.
I like the new Gosen Biogut especially the BS810, the feeling is much better than Roots Aermet. I try BG88Ti also but I'll prefer BS810. YY Cyber Natural 100 will be available on March.
Ricky, please update us on how durable this string is in the future. I notice the Aermet can break easily if there is a mishit of the shuttle against the edges of the frame.
I really want to try the Biogut Tournament but I couldn't find it even in shuttlehouse ~2 weeks ago. For Biogut Aermet, I personally still found it relatively hard (but probably better than Roots Aermet). However it is very good for smashes, with comparable performance of string like BG75Ti (it is definitely a better string than BG75Ti overall). BG88Ti is quite different in my opinion (I believe you are a hard hitting offensive player). Look forward for the Cyber Natural 100.
