What happens on a slight toe (side of the COG) strike - with Dr. Paul Wood comments

[Brian Manzella]

Please ask Dr. Wood how far off center you can hit before extra MOI, rearward CofG and gear effect become irrelevant... 1/2"?.. 1"??

From another scientist who would know, Fredrik Tuxen with research with the R&A....


Typical Iron : each 1/4th inch off of a perfect CoG aligned strike = 1.3° of twist

Typical Driver : each 1/4th inch off of a perfect CoG aligned strike = 1.0° of twist


The hits just keep coming....

I guess some people need better cameras! You might not see this with a Casio or alleged industrial camera and why would you? They aren't designed for this type of information. Phantom cameras!!!

The club is rotating about the shaft, so impact anywhere on the face will work against that (unless it is a massive heel hit on a centre shafted putter!)(

OK..so for an iron/driver, the rate of face closing is decreased at impact regardless of where the ball hits the club face?..but is there a compensation after that initial decrease in closure rate?

I know it twists.

Twist comes during and after impact and is only the 'effect'. I want to know how much the 'cause' is influenced... and how MOI, back CofM and gear effect can counteract varying off center hits. It's a clubhead design issue, not a swinging issue.
