Ok this is a 'my friend' one, so shoot me. I skied with this guy every time I was on the hill this year.
He had 'insert' Schizo Griffons on 169 KungFus.
He went through 3 pairs before getting a refund because the bindings would not stay in the same place on the track. He could start a run with both at +4 and by the time he got to the bottom one would be at center and the other at +3. Literally, at times it was that bad. He skies quite hard but in the 1 run I had on them they moved on me too. This was on 1-2 day old bindings.
The shop tried all sorts of things including Loctite on the track but nothing would make them stay in place so in the end they just said screw it and swapped the skis out.
Aside from the shifting around they were solid and skied just like a normal Griffon.
However. This year the Schizo is different. On the old ones when you turned the screw on the front it was smooth. On the new ones when you turn it there are detents in the screw so it makes a sort of soft click as you turn it. I believe this will be sufficient to prevent any more shifting around on the track. Unfortunately the importer down here had decided to only bring in non-insert bindings and skis this year (no point stocking double of everything in a market this small) so they couldn't be swapped for new ones.
Sparknotes: Cool idea, just doesn't work perfectly. Might be fixed now.
