No matter what other string I've tried, I seem to get the best result with this. Absolutely love the feel, touch, and rough surface which provides amazing control. Only downside is some initial tension loss which can be mitigated by a good stringer with ECP and prestretch.
the other problem is durability issue. because the outside texture is really rough, the mains and the cross basically cut into each other and after 1-2 sessions 3-4hrs per session, you can tell it's already worn. i literally watch it get worn out after each session.
another thing i like about this string is, whatever spot on the stringbed you hit the shuttle with, it gets worn out a bit, so over a period of time like 2-3 weeks, you'll see, supposedly, the sweet spot being most worn out, there you will see how consistent you are as well
and i also get the black color string so that when it's worn, the white shows up and that gives the best contrast and so it's easily noticeable.
