First, they are “legal”, we just have not sent them to the USGA for approval as of this date. If you are playing in a USGA event and are concerned someone will ask, then you should use another model until they get approved. If you are not playing in a USGA event, you can play them and not feel guilty about it. If you will notice, irons and wedges will only be on the USGA informational data base. This is the list for wedges and irons that they test for groove compliance. It is not a requirement to be on the list to be “legal”. It is a requirement to be on the list if the clubs are going to be used in a USGA event. The Informational Data Base is not the same as the Driver and Ball data base that requires drivers and golf balls to be on the list to be considered “Conforming”. Kind of confusing, but that is the way the USGA has it set up as of today and I always struggle to try and explain the difference. Not sure I really understand it myself. In short, no real excuses for us not to have sent the Tour Grind wedges in earlier. We are sending them in for the testing and should have them officially blessed by the USGA by spring. The M-Series+ .090 wedges have been sent in and are on the list.
