The new gummy Japan Rocs are very cool. I think some are just over 150g. How does it actually work in the Japan Open? Do they weigh the discs? Is it like 150 class and they allow a few grams over, or is it an honor system? I don't know if I'll ever get to play in the Japan Open, but I am curious.
They Japanese are very scrupulous. I believe they check every disc they get in Japan. They may also check the Japanese player's discs. They have not checked the American player's discs yet, but I wouldn't be surprised if they do in the future.
