Socket three
Mass away from the face, still a screw you can see
A back plug is not a launch button with a marketing name. It is grams parked rearward in a factory hole. The ball often leaves higher. Mishits often twist less. In 3,124-foot dry air that extra hang time is a gift and a problem, depending on the month.
January vs June
The same 8 g is not the same sheet
Indoor winter air in Suite 2 is still dry, but it is not a June tee on the rims. Tess from Red Lodge learned that the expensive way — an 8 g back plug that looked perfect on the net in January and kited in June. We dropped two grams in the same hole. The stamp never moved. The month did.
If your head has a sliding track, we treat it as a back socket with extra travel and still log the number. If your head has a single rear hex and nothing else, we will not invent heel and toe holes to keep you in the room.
Forward mass — emptying the back, loading a front hex if one exists — is the other walk. Some golfers want the ball to stay down in a Yellowstone breeze. That is a real request. It is also how you lose forgiveness. We write both outcomes on the sheet so you are not surprised on Saturday.
