Yes, but homer apparently found the value of a swing plane structure. For golfers who have no concept of Swinging on plane a visual like these structures is very helpful. The body must also learn it's new locations, and motions to accommodate the plane regardless of if they are precisely sensing the sweetspot plane. The c-plane is most accurately used by adjusting it to match your sweet spot plane angle and swing parallel to them, if you do not hit them and swing through air u have swung on plane, for some though it is very helpful to swing directly on the pads to get a feel.
Thanks Kevin. But here's the problem. In the video, Jeff is rotating the sweetspot around the shaft until it finally lies on the plane board with the shaft. At that point, the sweetspot hasn't shifted planes, but rather its plane gets deformed, making it 3 dimensional. But here's the bigger problem: The job of pp#3 is to feel the sweetspot and if any part of the shaft between pp#3 and the sweetspot touches anything, you will sense that contact point, rather than the sweetspot. The shaft must only touch AIR.
This is especially true with shorter shots......The putting arcs , inclined planes even a string line training aids are good but not quite right. A putter where the sweetspot plane lines up with the shaft would have more relevance I suppose with a string line.....itd only be off half a shaft width. The running of the clubhead along a guide could lead to a different motion or feel as you say. You could weight the putter heads heal to run along the arc say, something you dont do when making a normal stroke.
The string line which hits the shaft higher up will have more relevance than a device where the putter head rubs the arc or inclined plane. The thing about the arc devices is that you're covering the arc of approach rather than Tracing which is less than ideal to my mind.
I use them all to retrain my putting path and hinge action when its outa whack, but only for so long. They can tell you where youre off track quickly but you cant stay in those devices for too long......you gotta swing the sweetspot plane like you say, without running the club along something.
Homer thought we should all climb inside a plane board. That we'd all be very surprised by what we encountered, by where the plane is throughout the shot. They're very useful to my mind but somewhat compromised and/or simplified. No plane changes for instance but far better than the alternative ....
I am a big TGM fan but I cannot understand why you all aren't head over heels in love with the gyroswing? I mean, I' m FORCED to stay On plane when I use it. Plus, when one knows ones on plane it becomes considerably easier to focus on and feel the pressures points. I'm not talking about any particular plane but plane shifts don't affect pp's ... Do they?
Just like to say thanks to Lynn Blake over his great instructional videos. They've helped me enormously
My teacher uses the gyroswing A TON, very good training aid, for me it helps me rotate the club properly in the startup and not add any unnecessary right arm thrust. Gyroswing probably one of the best training aids invented...
stay tuned for updates on the cplane as I'm looking into manufacturing that will reduce the price and make this great training aid more affordable and higher quality for all
