No, but, as the bomb said "my memory is good on matters like these".
push down on the boot so as to make
the whole sole touch the ski..
You mean push the heel down those 2''?
Watch how the duckbill behaves and when and where it "catches"
against the bail..
In that Cobra, it is in good contact from the beginning. Only You get throwed on Your face by rocker launch (pardonne mois english - non-native speaker).
eventually it locks down with strong leverage against the bail..great for parallels..
To me, it seems quite the contrary. While the boot wedges duckbill into toe, it does so only because heel throw applies forward pressure (preload). But that won't stop the boot itself from twisting laterally, right?
Besides, that heavy, ever-cracking NTN Freedom Aluminum frame holds the white flex plate from sides, and I do believe that this is far, far better for parallels. At least I can not feel the negative difference judging against, say, Dynafit or current Marker (god forbid) offerings.
Tip the boot up and see how the duckbill works with the binding in the case of a tele..
Then the boot starts to twist even more - only one point of contact at the heel, and I suspect that You'll get squirreling ski because of that.
Double-barreled bindings might not have this behavior, but I do not know for sure.
A perfectly flat (not rockered) duckbill would not be desirable in either case..
Why? I believe that at least one 75mm binding actually helps to break bellows (given the duckbill, against which it leverages).
NTN, OTOH, helps breaking bellows even better.
But they
had to address boot twisting by overbuilding the boot mold AFAIK.
