Swing Path vs. Impact Point

Found this interesting, ive always thought that my hooks or slices were almost entirely an issue with face/path relationship. Ive also thought that gear effect normally just offsets the initial launch direction on off center hits. Any thoughts on this video?

Gear effect causes the ball to start left or right and then causes the ball to curve back toward the target.

Do a Google Image search for the term and you get lots of images like this:

So… yeah. Gear effect can cause "toe hooks" and "heel cuts." I'm sure you may have heard those phrases before, if you think about it.

Sorry if off topic a bit, but a quick google search did not reveal any answers so asking - why do irons not have a bulge built in the face? ROG or other reasons?

If I'm remembering right (might be totally wrong), I think it has to do with how little loft/spin is present on the driver compared to the irons

Is it true that metal woods have less gear effect than the older wooden woods?

You've seen those hybrid-like sets like the Bazooka "irons" right? I don't know that the Rules of Golf really determine this. I think a set of "irons" with "bulge and roll" would be allowed. So I don't think it's an RoG thing.

But think about the other reasons why you probably don't want your 7-iron to have varying loft and be pointing in different directions.

Irons still exhibit gear effect. If you toe a 4-iron, the spin axis is still tilted toward the draw side… and the ball still starts to the right, but neither as much as if you toe a 3W by the same amount. Partly due to the lesser deformation/ball speed, partly due to the lack of bulge/roll, partly due to the different placement of the CG (the iron head twists more easily, thus resisting the ball from making it twist less).
