There are generally two names used by the national team: hurricane and celestial pole. In addition to the nine numbers on the top of the rubber sponge, there is also a user's name, the word "country", and the words D39, T2.2 (hardness 39, 2.2 mm) are written on the bottom, which is for the national team members. This version is rarely circulated internationally, and is generally used by relevant personnel to find players from all over the world.
The other is the national madness without the user name and the word "Guo", with only the words D39 and T2.2 on the side. It is provided by the coach of the national team to some very familiar shops. As far as I know, the blue sponge in national madness should be Gale 2, because Gale 2 uses Haiyun 22# sponge, which is generally blue, and Gale 3 uses Haiyun 20# sponge, which is generally orange.
"Guo Tao" trademark is a brand created by Double Happiness Company for amateur golfers or other professional players with professional standards. The products are basically the same as those used by the national team, and they are also sold in the market now. It is basically divided into Guo Taobiao 3, Guo Taobiao 2 and Guo Taotian Ridge 3. Guo Tao's products are all produced in the research factory of Double Happiness Company, and other rubber covers are all produced in the ordinary assembly line of Double Happiness Company.
Many amateur golfers around me spent more than 400 yuan on national caps. Basically, I bought the national cap 3 and the national cap 2, and there were yellow sponges and blue sponges. Basically, 20# sponges and 22# sponges were transported to the sea.
Many people find that they can't control this rubber sleeve at all during use. Why? You probably know the answer: the flexibility is too great, and the time of playing the board is longer than that of saving madness, so you can't play at all!
