Ted,Which plane line to trace?

[KevCarter]

when tracing the club moves on a slight arc, even though you trace a straight line. Try putting a shaft an a low bench or coffe table, shoe box or something of the sort. Watch the clubhead back andthrough and you will see it moves on an arc.
Covering keeps the clubhead more on the plane line then inside to inside

coolstv88,

In addition, would it be appropriate to add that in tracing, the #3 Pressure Point is always pointed at the straight plane line while the club head moves on the arc, and in covering, the club head is always on top of the straight plane line? Covering is a bad thing as it equals steering...

EDIT, sorry, YodasLuke beat me to it, and he said it so much better...
