Recently i try Victor string VBS66Nano. For its performance is good for me but 3 days playing 3 hour each, i notice some paint chip on the string. The string turn white. I check closely if my string is about to snap but it turn out just the painting. No performance loss tho but never happen to me for other string i try (Yonex & Lining).
Didn't find that issue on this string.. This is actually a very decent string imo better than VBS63. It could be a stringing issue where the coating was accidentally chipped during weaving, tensioning, rough pulling, improper use of tools, poor clamping..
