I've been thinking about the sweetspot plane versus the shaft plane some more and came up with the following thought experiment:

Perform your normal swing with a golf club.

Now imagine that the clubface is stretched out horizontally more such that it looks more like a hockey stick - let's say one foot long. The sweet spot remains centered in the club face and is now much further away from you. The shaft length and lie angle stay the same. Imagine swinging this club.

Now imagine that the clubface is stretched even more such that it is stretched out to something crazy like fifteen feet long. Imagine swinging this club.

In your imaginary swings, did the motion and/or plane of the club shaft during the swing differ between the three clubs or was it the same? If it differed, how did it differ? I'd be interested in people's opinions on this (or if somebody can build the clubs and video that would be even better!).
