Gear Effect with Irons

October 26th, 2009
Let’s start with a chart from trackman. Basically, what this chart shows is how off center hits effect the flight of the ball. Trackman determines a theoretical ball flight based on the d plane and it’s impact conditions it measures. Based on the actual flight of the ball, trackman computes where the ball must have hit the face to create the actual ball flight relative to the theoretical flight that should have occured.

This chart from trackman has encouraged me to ask some serious questions about it’s validity and accuracy. Depending on the iron head, the location of the cog and a few other factors the amount of gear effect should change.

To simplify into a one size fits all system seems below trackman, so I’m going to dig for answers.

I’ve started an extensive research project with some of the best in the world. A club fitter from the UK, an engineer, a trackman employee/teacher from the UK and myself. I’ll keep you posted on what turns up.

I’ll keep you posted.

Squaring the Clubface First

October 24th, 2009
I’ve posed a question on a bunch of forum’s about this topic and I haven’t received enough of a reply to be happy with. I’m gonna say for the record books that I believe players know/feel face relative to path more than they know/feel face relative to target.

Here’s my reasoning. I tend to try and picture the first day a player says they’re going to take the game seriously and they head out to the range. I believe they look at a target and try to make the ball go there. It could be argued that they try to make contact first then try to make the ball go in the air. Fair argument. Let’s say they have conqured those two and now they want the ball to go to a specific place.

I don’t think it is reasonable to imagine that this golfer would figure out the face first. I think it is much more likely that they get some path that is relatively toward the target with a face that is so far open that the ball goes way right. They are starting to build a relationship between what the club face feels like relative to the direction it is going. They probably don’t know they are building this relationship but they are.

I agree with Brian Manzella when he says all the other stuff that people do on the way back to the ball is to try and get that ball to go where they are looking. Most slicers will choose some sort of swinging left to try and make the ball go less right.

They usually get to a point where the ball starts close to or left of the target. Some D Plane people and Trackman would call that a closed face because they choose to use the target line as the line that determines open and closed. However, to the golfer, there is no way it feels closed. I believe closed is relative to the swing not the target.

All slicers need to learn how to feel closed relative to the path to begin to fix their slice. I know a great many teachers that will choose to fix a slicers over the top move before they fix the face. The golfer will feel no change in the face/path relationship with this method. I do believe that some may figure out they need to do something with the face different if we swing more right but most will not.

As teacher’s, we need to teach them how to feel face relative to path because this is how they can relate to the club during the motion. The clubface is trying to open for most of the downswing. We need to teach them how to fight this feeling(coined gravity torque by Damon Lucas) so they can get that face more square.

I want my slicers hitting pulls and pull hooks as soon as possible so I know they know they are doing something different to the clubface. After they see a bunch of balls go way left, they will be much more willing to try and swing a little more right.

30 Minute or 1 Hour Lesson?

October 19th, 2009
I do lots of research. More time than my wife can appreciate. I do this research because I don’t like sucking. If someone is going to work all day, and that amount of money is going to go toward a golf lesson, I want them better when they leave. At the very least, I want them to hit one shot better during the lesson and to have an idea and set of drills to do to make that happen more often.

Virtually every lesson has multiple routes for approaching the issue. Part of becoming a great teacher is diagnosing the issue. The other part is prescribing the right ‘medicine’ to cure what ails. After that, you need to have a long term plan for where this golfer should end up if they stay with you for awhile.

For me, the real trick is blending all of these things together in the span of 30 minutes or an hour. The better I feel I become as a teacher, the more time I feel I need to help the player in these three areas.

I was taught that if you can’t fix a person in 10-15 minutes, you didn’t know what you were doing. An hour lesson is way too long because you spend most of the time watching them hit after the lesson. This all made sense so I did mainly 30 minute lessons.

Granted, there is a cost issue as well. The 30 minute lessons are cheaper and more popular yet the hour or longer lessons produce better and longer lasting results. For me, the longer lessons give me more time to see more of what they do.

Is it better to have 2 or 3 hours lessons that cover a wide array of topics or is that just too much? I continue to struggle with this one.

My main goal for writing this blog is to inform my students that I cam constantly trying to improve. Both in the factuality of the information I am giving and in the order of the information given. This second area is where I still see the greatest room for improvement.

Angle of Attack

October 11th, 2009
I was on the lesson tee today working with a young beginner and like most he was trying to lift the ball in the air. I talked to him about how we should strike the ground after the ball and how that it is accomplished. We tried a couple different things but nothing seemed to get through. I couldn’t get him to picture a steeper angle of attack.

So, I came up with a new visulization on the fly and here’s how it goes. I asked him if he had ever skipped stones before. He’s pretty young but he said, “Sure, at our cottage.” I said great. So, I set out a towel on the ground and we backed away about 30 feel or so. I asked him to throw a ball like he was skipping a stone and try to fly the ball and land it on the towel. He gave it a nice and low sidearm throw but never really came close. I asked him if he could see how low the ball was and how shallow the angle to the target was. He said sure.

Then I told him to move up until he was six feet away. Make the same side arm throw and see how you do now. Obviously, he hit the towel everytime. Then I asked him if the ball angle of attack into the towel had changed. He said, “Yea, it’s more up and down instead of across now.”

Perfect. That’s what we need the club head to do. Your angle of attack was too similar to that far side arm throw. Within 2 balls, he was striking the ball then the turf and he had a bunch more speed with it. So I asked him how it felt different. He told me that he felt like he was trying to hit the ball so it would go deep into the ground.

Perfect, great picture. I really liked this picture. It made it very obvious why we want the clubhead to come in with a bent right wrist vs. a straight right wrist.

I hope this picture helps everyone.

Increase Driving Distance

October 9th, 2009

A few months ago, a professional long driver came to our course to conduct a clinic. He gave some golf lessons on how to hit the ball farther. He was a big guy. Tall and well built but his swing didn’t seem overly dynamic.

The thing that interested me the most was his knowledge of the swing and distance maximization. He knew to aim right if he was going to swing up(D Plane knowledgable). He knew to swing up on the ball. This allowed him to use a 5* driver. It’s the ability to use lower lofted drivers that reduces the spin. As long as they can get a launch angle high enough to keep to ball in the air. Let me tell ya. This guy hit it a mile in the air with a 5* driver. Very impressive.

As I look at most of my students that I have taught for a while. Distance is one of the things they all share. I like it when my player’s pound it. I’ve said before many times that I teach speed first and accuracy second.

If you want to hit it long, focus on relaxing the wrists and turning as hard as you can.
