1) Weaker grips and much more visually flat left wrists will cure more golfers than stronger grips in the both the short term and the long term. Brian has said this for as long as i have known him, but i have figured out the "why" behind it.

Why? Well, before I answer let's see if anyone else can figure it out and Tom and Brian have to stay quiet ;). EdZ, you too!

2) Hitters resisting impact deceleration better than swingers is easily VISUALLY seen via launch monitors which i realized this weekend. By using so much muscular thrust via the right arm you can create a better smash factor ratio (ball speed / swing speed). It was interesting to see how much higher the smash factors were compared to swingers.

That's it, i'm done for now :)

Sure, i was doing launch monitor fittings at my friend's shop in NC this past weekend. We had some really solid ballstrikers there, mostly swingers. Even one person who was swinging in the neighborhood of 116-122 on the monitor in doors. This is especially noteworthy because most people tend to swing slower in doors.

Anyway, most of the "better" ball strikers were swingers and achieving smash factors in the range of 1.47-1.51. For those who do not know, 1.50 is the "supposed" perfect number but i have been playing with those for a while and know you can squeak a little more than that out of them.

So there was this one guy who i was fitting, REALLY BIG. Maybe 6'3" and over 250lbs and basically picked the club straight up and just hammered it back down. Pure hitter if i ever saw one, even with his "crappiest" numbers most of his smash factor numbers were in the 1.49-1.56 range.

For reference long drivers have been known to get smash factors very close to the 1.60 range and those guys swing a good 25-30mph faster than the hitter i had on the monitor.

Nope, keep guessing.

Hint: has to do more with what happens past impact

IYO . Is it that the Manzella neutral grip is more conducive to correct horizontal hinging past impact?

With the Manzella Neutral grip you can keep the left wrist flat during the finish swivel while keeping the clubface facing the plane.

The Manzella Neutral grip is also conducive to better distance control because it is easier to control your forward lean, and therefore, divot depth.

Ok, now's the time to demonstrate my ignorance again....

vjcapron:

Could you elaborate on your statement?

Thanks, Cliff

The statement above applies mostly to the scratch player and other low single-digit handicappers.

With a weak grip you are less likely to have too much forward lean of the clubshaft at impact, thereby you will hit the ball with the true loft of the clubface.

With a strong left hand grip a good player will have a tendency to deloft the clubface too much at impact due to too much forward lean of the clubshaft.

Johnny Miller attributed his weak left hand grip to his pristine distance control during his run in the 70's for exactly this reason.

Probably the best answer, however 2nd goes to maximizing #3 accumulator.

Basically a visually flat left wrist makes it easier to swivel properly past impact whether or not you choose to do by the book or the manzella way. It also pretty much ensures that there is not chicken wing through impact either; the more you are turning that left arm through impact the less it will have the tendency to bend.

If you look at the pics of 10-2-b - hold the book upsided down - you will see that the left hand V does not point to the right shoulder as in conventional golf teaching. The left hand and club face come close to lining up as in a conventional neutral grip. Just the thumb is palced on the aft side making for a large gap in the V.

That's nice, however it is still more "turned" than manzella neutral. If you do a search for "manzella neutral" you will see pics i posted of both grips and their corresponding flat left wrists at the top of the back stroke.
