Food for thought - how would a more flexible shaft with more offset (hook face) alter the way we see this forward bending?

How much does axis tilt play into the equation, if at all?

As long as thrust (lag pressure) is maintained and Rhythm and aiming point is correct, I see no reason that there should be forward shaft bend until AFTER seperation - indeed, ideally after both arms straight if at all.

The fact that so many people have this forward bend demonstrates how rare proper aiming point and Rhythm are - that people are not paying attention to 1-L-15, and that over acceleration happens with even the best of players.

Which Way?
 

Are you pondering whether a more flexible shaft will show forward bend easier or pre-stressing easier? I would say yes. A softer spring can be flexed easier either way. Of course our tour boys are very likely cranking X-flexes so the bend will be minimal no matter direction, especially since neither Janzen or Johnson are known for maximum length off the tee.

I don't think that swing speed is the deciding factor to sustain the pre-stressed clubshaft bend at Start Down. Sustain the Lag and you sustain the bend. Look at Lee Trevino in "Pros at Impact". That amount of Bend is not caused by speed.

I do think that regular or more flexible shafts can show more flex at impact but thats because they aren't stiff enough to rebound after the initial Start Down Shaft Bend.

Arms alone are nowhere close to the force developed by Axis Tilt and #4 Acc against the #3 PP to initiate the Clubshaft Bend and/or sustain it.

Not Necessarily What I Meant to Imply
 

Sustaining lag and hence bend is not a function of swing speed, but of technique (agree), however, magnitude of bend is a function of acceleration as well as shaft flex. Greater acceleration produces greater swing speed unless a countering deceleration occurs prior to impact (loss of lag).

Easier to maintain lag pressure without the forward kick - assuming proper technique, but certainly exposes improper technique easier as well.

Hmm? Swing speed is a function of Lag Pressure. The greater the pressure the greater the speed. Therefore the degree of bend is a function of Lag Pressure. 6-C-2-0 "Your "normal" pressure will move lighter Clubs faster and heavier Clubs slower...".

But, when in doubt, "high thrust, low speed" especially on shorter shots. High ratio of bend degree to speed.

Great Thread!
 

I am really enjoying this thread. Great stuff, everybody. Keep those cards and letters comin'! :)

What a post:laughing9 :laughing1 :toothy:

I see this so much in old books but rarely in Tour Pros video ,is this a deliberate use of an overstiff shaft in order to enhance direction control?,or too soft a shaft to enhance effective loft.Or is it good loading of the shaft PRIOR TO IMPACT to be certain of keeping it loaded through impact ?Is this what actually happens as opposed to what we feel.I would like to see the same swing with the shaft at impact-THE TRUTH!

It's hard to say with my uneducated eye. I'd need to see the left wrist at lowpoint. Man, these guys do so-much right.
