Tom, I’m your frequent flipper and I have discussed this with you in the fall last year. Trying to stop flipping has been a challenge for me, but after spending a winter in my basement hitting many practice balls, I have managed to almost stop and keeping the left wrist from breaking down through impact. So, today, in AZ, I took this new swing to the out door driving range and put it to the test.
First shoot good, second thru 8th, not so good. I was either hitting the ball thin or pulling to the left. All of a sudden, it dawned on me, I was not starting my downing with the “ bump”!
Once I started my down swing with the hips leading, the arms immediately started shallowing out and with my left wrist not flipping any more, the contact was CRUNCHY as all hell!!!
I just watched your video on more spine tilt and the left shoulder down, and will deploy this tomorrow. I felt, what it is like, to hit the ball crunchy and did it multiple times consistently, so I am psyched! The bump was important for me to get the proper swing sequence!
Just to make sure the "bump" motion is clear - the more the tailbone moves toward the target in the backswing, the LESS you need to bump.
Most high handicappers see a benefit to the bump because their tailbone does not move toward the target in the backswing, it does the opposite because they shift their weight backwards. They need to bump the most because they have shifted their weight more to the trail side in the backswing.
I've found that when loading weight into the front side - because of the tailbone moving to the target - I DON'T HAVE TO BUMP because the BUMP HAS BEEN PRESET by the tailbone motion in the backswing. See this photo (the tailbone movement is the yellow line):
