Anna Rawson is one of my choices. To quote one of my favorite movie lines from "Being There" with Peter Sellers, "I like to watch".

I wouldn't exactly classify him as an instructor, but my friend Peter Longo does a very informative presentation on the evolution of golf and the development of various swing theories. I just saw him give his talk (again) last week, and it helped my swing thought process a lot. (Also, he's pretty good on the electric bass. We met because his brother, Danny Long, is one of our favorite jazz pianists in the Phoenix area.)

Peter is a trick-shot artist, but he has also helped Sergio Garcia instruct many handicapped players over the years. Check out his website.

I like Don Trahan and Dave Seeman but you have to follow their vertical swing. I also like Ron Del Barrio, but again he teaches a swing. You can't really take bits and pieces.
Monty Scheinblum has lots of good videos, you just have to find the ones that apply to your game. There's really tons of guys with good stuff on youtube.

I watch them mostly for entertainment purposes. The Brits seem to be my favorites.
Mark Crossfield, Mark Shiels, Peter Finch, Dan Whittaker, Andrew Ainsworth, Teeuplo, Ali Taylor and Michael Newton.

I'd say Crossfield is a step above everyone else. His new format is quite clever and entertaining. He might be the most knowledgeable of the bunch also. If I were ever to take a lesson it would be with him.

While not an instructional video, this post reminded me of a YouTube video someone posted on FGI years ago, and was super defensive about any criticism anyone had to offer...specifically the opening dialogue.

I stumbled upon these guys back while living in London for a couple of years. They're very, very good... they keep the concepts simple, they use lots of neat diagrams and training aids during most of their online instructional segments, and just really break things down to where it's much more easy to understand.

And as they accurately point out in the video below, there's a huge difference between working on your golf swing haphazardly with drills on your own versus rehearsing the proper mechanics. They have a rather large library on YouTube and I've referenced their segments numerous times over the last several years to help me sort something out.

    In most of their videos they're dressed exactly alike. Which looks OK on the course, but would look a little weird off the course.

        Bebettergolf is somewhat entertaining. He has several videos where he goes around and does videos with other YouTube golf guys, like the one below with Bobby Lopez.

          Thank you!!! He doesn't know when to shut up and let the pro talk. Drives me nuts. He has one with Monte S. and he never shuts up.

            I came across Malaska late last year. Now, I follow Malaska and once the range was open at our course I started to work on his concept of the swing. What attracted me was his having transitioned from baseball to being a competitive golfer and the subsequent events of his career.

            I did not play golf as a youth, picked up my first golf club shortly after graduation from college because of encouragement from the work place. My best sport in school was baseball. My first experience with golf was to use a similar swing. I actually got better and better, never had a higher score than a 99, which was my first 18 holes at Papago, Phoenix and regularly broke 80 within two years playing about once a week and then did not play for another 10 years. When I started again I was in the low 80's and improving till I got some golf instruction and was told my swing was all wrong. Suddenly golf became a much more difficult sport for me than it had been up to that first lesson from a PGA professional instructor. So, I instantly related to Malaska when I heard the story of his career.

            I can't say I completely imitate the Malaska swing as I don't use a camera, etc., or have a good way to compare what I am doing to his video's. However, within a couple of small buckets, I was very comfortable with the changes I made. I decided to take it to the course. Contact was immediately improved, but I was reminded of my first exposure to the game. I was pulling the ball foul to left field. Each week I have seen improvement. Last round, even though I bogeyed 5 of the first 7 holes, I ended the round with a 79. What I really like is that once again the golf swing feels natural to me. I haven't yet, but I am now going to work on some of his short game concepts. Maybe the Malaska full swing is not for everyone, but imo if you are a baseball player or were in your youth, Malaska is worth checking out.

            This is one HUGE dose of Malaska all at once. I have watched most of his videos several times over and now I understand what he is saying here completely, but it was tough the first time I watched it. Give it a look and see what you think.

            I've tried his method on the range and at the course and when I do it right, it's unlike anything I can remember. The ball just sails straight as an arrow and there is virtually NO EFFORT to the swing. I have to keep fighting the tendency I have to start opening the shoulders almost immediately at the start of the downswing. If I can start with the hands moving straight down instead of "pulling the club" from the top, everything just falls into place and it feels amazing.

              Yeah, not sure what's up with that but they do wear the same colors most all the time. It's probably a brand-identifying concept that they paid some marketing expert several hundred pounds to research in an effort to establish their own appeal.

              Whatever works I guess.

                Bobby Lopez is very entertaining also. Great personality and great stories.

                  RV - take a look as some of the slow motion swings of Jack Nicklaus iron swings early in his career. Also look at some major league baseball swings. Bat drops creating lag, but remember they are hitting the ball in front of them. So you turn to close the gap. In golf the ball is on the ground and you want to hit it while the arch is still descending - so the room for the swing has to be preserved until you start the "release" as defined by both Nicklaus and Malaska. I find it interesting to note how almost all of Jacks turn and body motion took place after the ball was gone. Yet, the golf announcers always talked of his turn, weight shift, etc. as if it was why he was so long. I agree with Malaska - TV changed the perception of the golf swing.

                    Has anyone significantly lowered their handicap after watching instruction videos or taking lessons from a professional?
