1. Can anyone show me where, in the book, the terminology 'start up swivel' is used???
If not, then please, lets not use it. Of course, it may be used, hence, my request for a reference.
2. By swinger, lets define.
True swinger - centrifugal force rules, including the squaring of the clubface.
'Swinger' - utilizes centrifugal force for power (loading, etc) but not necessarily alignment of the clubface, and in this case, adjustments may need to be made.
And again, start up swivel please.....
