I’ll let you know how to change the club grip in the next patch.
Holding
Same as before. The club becomes visible only when you are holding the trigger.
Toggle
This is the new type of club grip. Pressing the trigger makes the club visible or invisible.
While you’re holding the club, you cannot go on to the Replay Screen or Swing Analysis. Also if you want to see your controller’s lay and press the UI button, you should release the club.
You can see the other details of the second patch in here.
