One thing I discovered about training devices is that they don't in themselves fix anything. You can't expect to start working with something and all the sudden wake up with an incredible swing. The "generic" type swing aids just have never helped me.

I have found they are only useful if you are working on 1 particular thing, like having a flat left wrist. Then they can provide useful feedback during your practise sessions. I think the simpler to use the better...

Right on, Keith.

Only when the correct Mechanic and its precision Alignments have been identified can you successfully Translate that Mechanic to its Feel Equivalent (Chapter 3). This is Homer Kelley's Star System of Golf: "Let Mechanics produce and Feel reproduce" (1-J).

Ideally, this Component Translation is accomplished under the trained eye of a competent Instructor. However, in lieu of that Instructor -- or in addition to that Instructor -- there are a handful of useful 'feedback' tools that will assist in the correct Translation.

Unfortunately, there are also many such devices that do not deliver the promised goods. Worse yet, they often do deliver the promised goods, but the goods don't work and are often counterproductive! At the 2005 PGA Merchandise Show this past week, I saw plenty of both types.

It occurs to me that it would make a terrific little video just to demonstrate some of these things: To explain what they purport to do and then show why that purpose is just so much nonsense. It would be kind of an Andy Rooney 60 Minutes thing. The problem with the idea is that, once the manufacturers got wind of my purpose, a demo product would suddenly be in short supply!
