This is Andro's Treiber CO. It's a Chinese-style penhold. It's an outer carbon racket. The forehand has Dignics 80 (2.1mm, I think), and the backhand has Moristo SP (I forgot the thickness). I've used Dignics 80 for about 2 months, and Moristo SP for about 2 weeks. The racket itself has no cracks, but the index finger area is worn down as shown in the photo. Thank you.
