I disagree with the absolute nature of your statement, Jim.
It does matter where your eyes are. It matters more that you have a straight gaze.
Why is it SO important to putt on a straight plane line? Especially with center shafted putters.
Did Bobby Locke? Crenshaw? Mickelson? Loren Roberts?
Is it because TGM says it's an imperative? Your own study of thousands of putters?
couple things:
1) I believe the plane line has to be straight to be a consistently great putter. Now that "straight line" can be pointing 10-20-30* right/left of a "square" plane line. That i don't care about. But If you want to put the ball on the line you intend to start the ball on there really is no reason why you shouldn't putt on a straight plane line. Now let me define what i mean by putting on a straight plane line: By this i mean to always have the sweet spot of the putter pointing to the plane line. I visually view this via using a laser attached to the putter shaft and point it to a straight line.
As an example, i could stand square but putt on an inside/out 30* plane line (that is straight) and make sure the face is closed enough at impact to negate that 30* inside/out path and the ball will still go on your intended line and still go in the hole. Same idea with an open stance.
2) Hitting the ball on the sweetspot is vital because the research i have read (and on my own and with students) you have a higher chance of still getting the ball on your intended line with the proper speed with a slightly "bent" plane line hitting the sweet spot that you do with a perfectly straight plane line and consistently hitting it all over the face. What i'm saying is that you can have more margin for error in your "path" than your "sweetspot contact" than the other way around and still "get away with it" so to speak.
So i guess you could say that your deviation from the line that you are trying to start the ball on will be more with a "perfect path" and "less sweetspot contact" and your deviation from the line will be less with a "slightly bent plane line" (path) but "perfect sweetspot contact.
3) Now let me go back and clarify what i mean by saying where the eyes look is not important. It does matter a lot when you are setting up to your putts because it will effect what you "see" and therefore your stroke will be manipulated because you are looking incorrectly at the ball. For instance i have a student who putts with an outside/in path with a closed face because he sets up with open shoulders and leans a bit left so his eyes make his vision of his path different. So where he is putting his eyes makes a huge difference for him.
Now the funny thing is that i could change his setup and get him more in a neutral position (which i like to see) and putt much more on a normal plane with more normal stroke through the ball but would he necessarily putt better? It's possible but it would take a whole lot of practice to learn that. If he was willing to do that i would but he isn't. So i am getting him to putt better but manipulating his setup so he can stroke it the same but the ball goes on the intended target line. So by slightly altering his aim (due to his faulty eye position) i am still allowing him to drop many putts.
-----------------
I guess what i should say is that when you have proper eye position for your setup/stroke whether or not they are "over the ball" or "slightly inside the ball" is irrevelant.

As for center shafted putters it is still valid to putt on a straight plane line. The shaft is still at an angle and the clubhead will still travel in an arc so you will always want that sweet spot pointing at the plane line.
Now students always ask me about straight back and straight through putting style. this is also very valid way to putt but the problem is you need a putter SETUP to putt this way. Ideally it is very short and very upright so your "arc" the putter head travels on much much less. I have talked to many students who have gone to Pelz putting schools and they all teach straight back and straight through with very short and very upright putters to eliminate the amount of arc the putter head travels on. Some people end up liking it and some people don't.
Whew...long post lol

homersson...i'd love to hear your comments on the above. Let's keep this post on point and informational for all to read.
Thanks
