Here are seven others to consider.
4. The angle of attack
5. The Path at impact
6. To control the Path and Angle the Slot position must be managed at transition.
7. The Low Point control aided by pulling the handle Normal.
8. The Jump
9. Impact must be preceded with the hands passing the right thigh.
10. How there is a boost in parametric acceleration when all the above are exercised.
My thinking at the moment is all about is focused impact
position, in an effort to get rid of a flip and the very high launch angle/ dynamic loft.
the things you mentioned are just possible ways of getting it done and certainly not fundamental to good impact, but could possibly be good for a ton of golfers.
That's good enough for me. I suspect I am one of the ton.
No love for the sweet spot?
I LOVE the sweetspot...I just haven't been to find it for a long time courtesy of 1) reverse pivot (all weight on left leg at top of BS); 2) underplane takeaway a with a corresponding over the top downswing, and the flip/ very high dynamic loft.
Reverse pivot and plane are much improved. Curing the flip and reducing the dynamic loft is a work in progress. BM has emphasized the need for my hands to be in front of ball at impact. In searching for that, I recognise that my club and left are create a straight line and my left wrist is straight.
The three fundamentals represent my current swing thoughts to curing the flip and reduce the dynamic loft.
