I remember installing a pair on my 205 White Star . It was 1979 ...
Never saw the difference - I don't cross my tips - until I went down a steep mogul slope in a resort close to here .
Then I saw that going from one top to the other ( my way of skiing moguls then ) my skis were crossing in the air but I was uncrossing them before hitting the next top .
Not with the Parablack !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
They crossed and they were staying crossed ...
I unglued the thing as soon as I got back home ..........
For a day , I was the coolest guy on the slopes .
