I would recommend a swing that focuses on keeping your weight forward like the stack and tilt

I have added a waggle to my full swing routine and strengthened my grip slightly as it had gotten too weak over the past year of playing such that I was slicing

At the risk of stating the obvious, I use a pendulum swing trying to rock the putter head the same distance in the back swing as the forward swing with the shoulders. Keeping my hands and arms soft but steady, the club face opens and closes with the swing. A short swing opens and closes less so it looks more sbst. I do not know about the drill.

I have read and continue to read The Golfing Machine. I tried the Stack and Tilt successfully about 5 years ago but hurt my knee and gave it up until last year after reading TGM. I have also read Jim Hardy's stuff on one plane - two plane swings and always assumed that the hitter was the one plane and swinger was the two plane. After watching this short video, I am not so sure.

go for it!

Lipout: I agree with everything you are saying. I am very analytical so I could tolerate going back and forth in TGM. I learned in 2006(?) about the (Hardy) two plane (swinger) and one plane (hitter) swings. Before that I tried to incorporate every tip that sounded good to me and I just got messed up. But now that I am reading TGM (over and over), I can weed out the swing tips and use the hitter tips. One thing that has particularly helped me is getting all of my swing thoughts moved into feel. I started playing golf at 46 so I never had a natural swing with good rhythm and tempo. That is just starting to come around. for me.
