I've very happy to share.
I started playing Golf 15 years ago and Dalton's videos where the first thing I ever watched (or read) that actually got me off the sofa and made me look in the mirror at my golf swing.
I had zero hand eye coordination skills and even to this day I am still a 'Golf by numbers' man rather than a 'feel player', but if I can do it anyone can, trust me! At the time (like most) I had a picture in my head of my swing looking like Tiger Woods. and of course when you really see it for the first time it is nothing like that! :-)
I will try my best to give you my take on the first videos, my favourite thing about them is that Dalton manages to get you to drop everything you think you know about Golf at the door so you start from scratch by telling you some stuff about the Golf industry, club fitting, etc...
I remember before I watched the videos asking someone for some tips for my swing and they said 'start again', I took that as a real insult and it made me very angry at the time, but he was right! the point is Dalton said it in a way that made you happily start at the beginning as you felt you would come out the other side hitting straight shots. I haven't watched PureStrike, but I have never seen any instruction on Golf that manages to de-programme you and then re-programme you with a whole new swing like Dalton's. I often wonder why more coaching videos haven't followed suit as this to me was the real key. (Learn one technique from scratch, rather than just adopting bits from different stuff).
The fundamentals he teaches are pretty much 'Hogan's Five Lessons' and he references this in both the old and new videos.
The 'Big Key' to why so many people get and love his teaching is the way he teaches it and the why he words stuff. The best way I can describe it is like the lyrics of a song, He takes something that would take me 4 pages to describe to someone and does it in a paragraph, therefore it is so much easier to understand. Rather than your brain trying to retain loads of information as someone talks 'at' you, he explains it very simply and often uses little 'key saying' that you will just remember for the rest of your life. So when you go to the driving range and you are working on stuff the 'saying' pops in to your head rather than trying to remember everything your 'Pro' told you at your last lesson. He is probably not the first to do this, from talking with him, he is a massive fan of Harvey Penick's Little Red Book and again he references this in the new video.
The best example of 'meat' I can give you from the first video is the way he explains the grip. before watch the video I was using and interlocking grip and I'd had a couple of lessons where the Pro changed me to an overlapping grip and it took weeks/months to even feel right. When I watched Dalton's old video for the first time he didn't just explain the grip, he explained how the muscles in my arms work. He explains that your little finger, ring finger and middle finger control the inner muscles in your arm and these are the controlling muscles and your index finger and thumb are connected to your outer muscles which are your power muscles. He was the first and only person in 15 years to teach me that!
Within 3 months of watching the videos I went from never breaking 100 to shooting in the mid-low 80's
In the interest of be constructive, the issue I found with the tapes was hitting my Woods, I became very good at flushing my irons, but would often leak my Woods right (I later discovered I had a very steep swing plane) , while trying to improve my tee shots I started having lessons and my local Pro totally ripped my swing to pieces.
I spent the next 10 years going from reading books, to watching videos, to having different lessons with lots of different Pro's and watching my Golf go up and down.
A couple of years ago I decided to embark on another swing re-build (which I have done many times!) as I wanted my swing to look picture perfect on camera as I was going to be doing a lot of club testing. The guy I ended up working with for about six months (I'm guessing) taught some of the principles of "The Golf Machine". He had my clubface closed at address, my first move was up and out, rotating to a 70-80% rotation (if you consider the club head parallel to the ground at the top 100%). On the down swing I was trying to hold my wrist angle as long as possible to a low and left finish. I got to admit is was super straight! the biggest problem I had was a little block right if my timing was off.
There were a couple of "alarm bells" over the six months I worked with him, the main one was "The Long Thumb", he wanted my grip very strong with my left thumb as long as I could make it which lead to a couple of strains and pains in my left hand.
Later that year I played in a Charity Pro-am with the Senior European Tour. I was paired with a guy called George Ryall, who I have played with a couple of times in the past and we get on really well. So we used the day as a bit of a catch up, he told me about the Tour and I told him about the stuff I was up to. I said I was finally getting more confident with the level of Golf I play and will probably look to do more Golf stuff next year and that I may even finally do my PGA, to which he replied "not with that swing". After a long conversation with him and some of the other Tour guys (All Senior)at the dinner table I ended up spending three days with him doing a 12 hour a day boot camp.
What George wanted to teach me was effectively "Clock Face Golf" (which undone the other technique), as we went over the fundaments again and again, everything he was saying just reminded me of watching Dalton's videos, when I got back the first thing I did was re-watch them (first time in 8 years), which is where I'm at now (with a slightly flatter swing plane).
I think the reason I find the original technique works so well for me is it is the first technique I learnt and that has created "natural tendencies" in my golf swing, when I rebuild/change my swing I find myself fighting these tendencies, which I can do on the range no problem, but "coming down the straight on Sunday" is sometimes a different story.
To give you an idea of the differences between 'The Golfing Machine' swing and 'Straight Talking Golf'. With the Golfing Machine I was always fighting to try and keep my right foot planted to allow space for my arms on the downswing, with STG that is not an issues for me I can just let my body turn as it wants to. Also as I am not trying to 'Lag' the club anymore and 'hold off' my release I generate a lot more club speed with a lot less effort. The other technique may work really well for some Tour players but I am nowhere near at strong as those guys, Tiger is like (He-Man). I also find that the STG swing allows me to hit the ball 'dead straight'. Which means I now find it al lot easier to shape the ball both ways (with the Golfing Machine it's very hard to hit a draw).
As I said before I am a 'Golf by numbers' kind of guy here are some of my Stats:
Golfing Machine Swing:
3 iron, Club head speed 87mph, Ball Speed 120, Distance 192
6 iron, Club head speed 83mph, Ball Speed 115, Distance 165
Straight Talking Golf:
3 iron, Club head speed 92mph, Ball Speed 130, Distance 210
6 iron, Club head speed 88mph, Ball Speed 118, Distance 180
*the distances do not really matter so much as I have several different sets of clubs, but these numbers were taken with the same set. (I have several sets of blades and cavities and they all launch at different angels so travel different distances, but I I'm guessing this is a discussion for another thread).
So my friends, this is the geneses for 'Straight Talking Golf', I contacted Dalton last year and after a lot of discussion we decided to work together and we set about re-shooting the old tapes. I have spoken with a lot of very happy students this year as I was trying to figure out how we could improve them. I also had an input I on the things I found hard to understand the first time and hopefully the new version is an improvement on the first (If that is possible).
The reason people are reluctant to share information with you is simple, it works! :-)
