Fluffy said:What year was the 'sine wave' introduced? I know it was before 1983-84 when the ATA left the ITF.
As I said, the USTF is what the ITF should be. Good group with great leadership.
I was training w/ some USTF/ITF folks for a seminar in the late 80's/ early 90's & they "introduced" the sine wave to us as "something new" at that time. But I agree about them being solid.
