Slide,
My feelings about Al's book are not changed. Due to a bunch of "life stuff", I have not played much in the past month. But I do practice almost daily the things Al promotes, hoping it will start to feel natural, just as the modules start to feel more normal to me as time goes by.
A tip that Styles gave about using a short dowel ( I used a magic marker ) helped me diagnose a tendency to strike the putt with an open face....and in retrospect I believe this has gone on for years, maybe decades

. Thanks, Styles, to you also for that drill.
Al's book gives a good prescription for this, as now I can hit the magic marker straight most of the time.
Another drill becoming a favorite of mine is to stroke putts on a yardstick, using one of those old
two-
colored Ping balls. A true roll can be seen with this ball, and will roll the length of the yardstick ( or meter stick) as one gets more proficient. This is an old drill of Horton Smith's, I think, and another good diagnostic tool.
I am pretty sure Loran Robert's stroke is what Al is advising.....so I'm not sure you can get much better than that. I think he has been shown to start with his clubface 2 degees closed(R3J says), then hoods it even more on the backstroke......which in my way of thinking, he is simply pre-setting the "hood" or "tuck" that Al speaks of. I think Dave Stockton's method is similar to AL's also, and Geoff Mandrum rates Stockton as one of the best putter's of all time.
All that from me, one of the worst, but still loving and devoted to Al's method, and grateful to him. I've stepped up and made some 8-15 footers I never made before. Hopefully I will be able to give observations of real life experiences through the summer.
Good luck Slide.....hope you are as happy with it as me. I recommend printing the book, it made it easier for me to read and make notes.
