I used to own 180cm 244 usa's, back in the day (1978-I was 14).
They were my first real performance skis - they were fundamental to my evolution as a young ripper. Segmented foam core with fiberglass ribs(similar to the old Dynastar Omeglass); they were light, with a very soft, round flex. NOT torsionally stiff. They were fun and lively, but sacked out quickly and the soft bases were mangled. Ever try patching a bright white base with a black P-Tex candle? Heh.
I moved on to the 204cm 255 Soft the following year. That was another fun one...
My dad was skiing the 180cm 244 Short at this time...he loved them. I distinctly remember their distinctly shapely geometry: much fatter shovel & tail, and much more sidecut than most skis of the era, somewhat similar to 'modern' designs.
I blew up several pairs of K2 during Jr. High/High School. They just didn't hold up to abuse very well.
Some things never change.
