i heard this too......but i have the Griffon Schizos from like 4 years ago.....and i have had absolutely zero problems(btw i ski pretty hard) . But i have heard plenty of stories of them breaking, so i just musta got lucky. Also i dont really use the moving system at all....i found it more of a hassle really. so i would just go with a normal binding if i were you. you wont feel a difference really in 1cm anyway.
Just my 2 cents.
