Yes he is using AC102. His brand name grip is for commercial in Malaysia. He is sponsored by Yonex. You have to remember that.
Anyone knows how he puts the overgrips without using a finishing tape? An illustration/pic would be a great help.
Don't start wrapping the grip from the sticky part, use the other side, and then finish with the sticky part, so that that you can finish without the finishing tape. You're pretty much gripping starting from the opposite side of the tape.
