This reminds me of some of the things Grady did.
You mentioned Grady, We were very good friends for many years and had several conversations about, Stroke/Effect (English) Banking (Kicking).
I shared some of my, Techniques/Theories/Systems with him. Some were demonstrated in his work.
I'll relate a little story from the mid 90's, A retired CPD/pool player was having a Grand Opening for his new room on the Northwest side in Chicago.
Being from Chicago, he asked if I would hold a 3C clinic/Artistic 3C shots for the event.
He also told me he had contacted, Grady and Mike Massey at the same time to do respectively the same in Pool.
As I stated, Grady and I had been friends and were happy to be working together! I had met Mike a few times on the road, but not personally.
The event took place on Saturday afternoon/evening. I was up first around noon with a fundamental 3C clinic, I would be back around 7pm for an exhibition of 3C Trick shots.
Around 2pm Grady displayed his talents/knowledge in 9 ball and 1 pocket. Mike was to close out the show around 9pm that evening with his wonderful exhibition of Pool tricks/Stroke!
All three of us talked together throughout the day, when it came to my time to perform, Mike and Grady watched the show. Grady gave Mike a little 411 on my show.
I went through my routine, and it went very well that night! Most shots being made on the 1st or 2nd attempt, only trying in 3 attempts on all shots.
When it was over, Mike came running over to me and asked,
"How do you get so much action on the cue ball, without hitting it hard?"
I explained a lot of practice with the correct, 'Concepts/Techniques' I learned from Great 3C Champions that were excellent Artistic players.
Like Juan Navarro, Marcelo Lopez both from Argentina and Louis Campos, Roberto Rojas form Mexico.
Mike went on that night to Wow the crowd with his, 'Powerful Stroke'!
