But...If you keep the right below the left...how do you keep from over rotating the left arm on the backswing?

Slick, easy to understand. Great video - thanks.

Q1: What are Steve's smash factor #s for his short irons and are they lower than say a Lucas Glover type?
Q1a: Does the lack of wrist cock and lag (+ GUTMarbles move) create more consistent distances with his short irons than someone who swings it like Glover?

Keeping the right elbow lower in the downswing tends to open the club face. I think I can come up with some, but what move(s) help to combat this?

Spin loft can be thought of as a measure of how oblique impact is - or how divergent path and face are. But the more divergent the path vector and the clubface normal, the less the ball is going to compress for a given clubhead speed..

Just to confirm my understanding, smash factor is maximized when AOA equals dynamic loft? Anyone?

My understanding is that smash is just a term used to describe the ratio of ball speed to club speed. Smash is maximized when the ball speed tops out at a designated ratio above club speed (1.495 is the current limit). Drivers and 3woods can get there (and even above), but neither with dynamic lofts equaling their attack angles.

If we’re talking theoretical smash numbers… I think 2.00 would be the max possible. But in addition to the unrealistic launch conditions, you would also need a face material that would allow for 100% energy transfer back to the ball.

No, because you could have 10* of dynamic loft and a 10* angle of attack but you'd have more compression if you have less angle of attack which is why someone said spin loft.

I am still confused Jim. In the video Brian talks about compression - how well he uses his clubhead speed and turns it into ball speed i.e. smash factor, then at 3:04 he says to do that "You have to get the dynamic loft and the attack angle as close together as possible"

It's the reduction in spin loft. If you go from a 30 dynamic loft with -3 AA to a 25 dynamic loft with same AA, you are increasing the compression (and smash). Getting them "close together as possible" in this case is not the same as getting them the same. The spin loft needs to be appropriate/useful for the club being hit.

drewyallop- think of the case of maximum compression, e.g. a punch with my fist to the wall...the spin loft is zero because the front end of my fist (the clubface) is parallel to the wall and perpendicular to the direction of travel (sweetspot path) which is horizontal. If I increase angle of attack by hitting down on the wall, while keeping my fist angle the same so my fingers still contact the wall in the same way as the first example, there would be a non-zero amount of spin loft, so it would not be maximally compressed.

I posted much earlier on watching a Canadian Tour player hit irons from down the line. Even given the gross inaccuracies of drawing conclusions from untutored observation I was amazed at how the club head seemed almost horizontal with the ground so far behind the ball. And the impact seemingly right square into the back of the ball. And the ball not seeming to go that fast but it just kept going. The whole swing seemed effortless given the distance achieved.

Just once I want to make this swing.

I'm with you on that. I think I have actually done this a couple times, but only a couple.

Sadly, for me spktho it is random.

This thread got me to thinking about the older golfer. Me, I am 66, good strength, bad back, slow swing speed. I golf with an eighty year old with a loopy slow swing but manages to drive it 210. The only explanation is optimum impact conditions. My thought is that the most important thing to teach the old is impact. Once the student realizes how much distance is available without all the sturm und drang of big pivots, x factor, hip speed, in short without trying to be a tour 25 year old, then maybe the game becomes easier and more satisfying.

Of course, launch monitors and 3D motion tools and great teachers are essential for this kind of teaching.
