Dear Jeff,
Here's an insight that may be helpful. I've just spent six days watching PGA Tour pros putting and another one day watching Buy.com pros putting, and I learned something interesting: A short putter has a slower tempo than a mid-size putter and is as slow or slower than a 35" putter.
The reason is the tempo depends upon the length of the system, from putterhead to pivot. Tnger the system, the slower the pendulum tempo. For a 30" putter, the golfer hangs his arms so the shape looks like a V without much elbow flex. With a 35" putter, the golfer's arms usually look like a Y with plenty of elbow flex. That's because these putters are too long to allow hanging the arms AND placing the eyes over the ball. The upshot is that the short putter creates a body position for the total system that is longer from pivot to putterhead (or at least not any shorter) than the system that results from a 35" putter.
This is even clearer with a mid-size putter. The mid-size putter derives from Phil Rodgers and Paul Runyan somewhere back in the 1960s (I think that's the time frame). The technique has the top of the putter handle placed against the sternum or stomach and secured there. This means the sternum / stomach just above the waist is the pivot. The putterhead-pivot distance, then is SHORTER with this putter than the system for a short 30" putter.
As a result, the short putter is smoother, works more closelty with gravity, and promotes better targeting and hand-eye coordination.
Applying this analysis to the broomstick, it would seem that this ought to have a slow tempo too. A typical broomstick is about 54" long. With the butt of the handle secured against the upper chest about heart-high, it would seem this would result in a tempo slower than a short 30" putter, but does it? I don't think it does. The typical length of a short-putter system with a 30" putter is about the same (54" or 4.5' from putterhead to pivot. If you measure this distance on a typical 6.0' males at address, it comes out about 54".
Tempo is just one factor in the technique mix, but to me it is one of the biggest factors. So I thought you might like to consider these points.
Cheers!
