However, based on what you said about the non-hooking aspect with good players, I knew there must be a case of mistaken identity. So, I visited their website at www.tempomaster.com and found that we do indeed have a different animal, a Son of Whippy so to speak. The shaft is much thinner and appears to be even whippier, but having never swung one, I cannot say.
Nevertheless, it really shouldn't matter, because the Laws are still the same, i.e., the Sweetspot is still trying to get in line with the first joint of the Right Trigger Finger. And at speed, a weak shaft will lag and the distorted shaft will cause the Clubface to close in relation to the original hookface built into the Club. That is not a new phenomeon: it has plagued good golfers for centuries. Not until the advent of the modern steel shaft was the problem minimized.
But here we have a mystery. A Mr. Whippy whose weak shaft purportedly does not distort the Clubface alignment even when swung at speed. That means one of two things or both: (1) The pencil-thin Shaft (aided possibly by its material) is permitting the Shaft to act much more like a piece of string, i.e., it is not producing the abnormal torque of old that closed the Clubface; or (2) the Whippy's Clubface is set more open than for normal clubs. I've got an email out to the company asking for clubface specifications. If they provide them, it may shed some light on the situation.

The above quote from an earlier post highlighted my perplexity regarding anapparent override of the Laws of Force and Motion.
For the record, I have received word from Mr. Whippy's manufacturer that theDriver's Clubface is set two degrees open.
