EDIT: if someone has access the the critical angle gif it sure would help the explanation.
David MacPhail does - but he also supplies the answer to how to go past critical angle: whole leg rotation of the big toe into the snow.

I don't have a gif, but I've got this explaining Platform Angle. Is that what you mean by "critical angle"? C2 shows what happens when you "go past it." Assuming hard snow.You don't have to be at the critical angle; you just can't go past it....

OK, I'll bite. How is "Platform Angle" defined in this usage? Which "Platform" is being referred to?. And what are the red arrows (vectors?) indicating?I don't have a gif, but I've got this explaining Platform Angle. Is that what you mean by "critical angle"?

Enquiring minds want to know!
Good adviceAdjust platform angle by moving where your center of mass is, not by changing your ski's edge angle to the snow. In other words, angulate out over your outside ski if you want it to not skid.
This last season this was my preferred way of dealing with the relationship of CoM to BoS. I moved my feet under me, from up under, to out and around, then back up under. This is a different movement pattern than the usual, and definitely a different conceptualization of how balance and grip can be controlled.
Not all skis like that , as Phil mention in post #12.Something else that needs to be remembered with turn Radius is risk.
The smaller the radius the greater the risk at higher speed of catching an edge (tune not withstanding). This is most noticed on shorter length skis.
So the idea zone for speed vs turn ability vs risk is somewhere between 16+m and below about 20m. Larger to smaller from this range shifts the balance.
Again as @Philpug stated these are only guides not absolutes.
Very short ski for those speeds. I would suggest that this despite doable with a ski like this it not a good idea. For a ski to have that tight of radius it will have shape no matter how it is constructed and therefore put you at risk as the rear edge can catch leading to a world of hurt.Not all skis like that , as Phil mention in post #12.
Try Fisher The Curv GT and you will see.
I am 6 feet , My Fisher The Curv GT skis are 168 with 14m radius , My average normal skiing day is speed is 50mph, this season I hit 65mph and did not have any problem handling it at all, not even one sec felt difference in balance. As we know this is triple radius ski so it really matter of construction of the ski.
Just Demo them and you will see what I am talking about , they are different animal.Very short ski for those speeds. I would suggest that this despite doable with a ski like this it not a good idea.

Again, speaking in general guidelines, not a good idea.
Which knee thread?Do you have the one showing platform angle and GRF with different ski widths? (And could you post it to the knee thread?)
In comparison to my SL’s if they where edged like that you’d be doing twice as many turns. I suspect that they have earlier rise tip and tail which slows down the turn in. My son has a set of Rossi’s which are similar, extremely pleasant to ski and while a nice ski (something I might consider when I get older), just not responsive enough for me.Just Demo them and you will see what I am talking about , they are different animal.
I got that size because of the short Slalom turns , which I love to do it .
Here is vieo I got it 2 years ago , this is 45-50mph:
Comparison Review - An intermediate oompa-loompa's comparison: Head Rally vs Fischer The Curv GT
I've had the chance to A/B these skis in the last week, in Australian early season conditions - mostly man-made snow, firm, fast early morning pistes deteriorating quickly with the dense crowds to choppy slop or push piles on a hard base. The Head Rally's are huge fun and so carvy on the early...www.pugski.com
Rossi's are way different , plus they use Rocker at tip, Those Fishers are full camber .In comparison to my SL’s if they where edged like that you’d be doing twice as many turns. I suspect that they have earlier rise tip and tail which slows down the turn in. My son has a set of Rossi’s which are similar, extremely pleasant to ski and while a nice ski (something I might consider when I get older), just not responsive enough for me.
IMHO early rise tempers the ski responsiveness which allows for easier progression of turns at speeds (race skis are starting to do this just a little) down side is that it can lead to false sense of security and if it catches it will catch you completely off guard.
Just be aware if you ever get a more aggressive tune (or hanging burr) you could be in for an injury. 168 at the speeds you suggest is an injury in the making.
Which knee thread?
It's not that it can't be done, but it certainly can't be done comfortably. I did 100km/h (close to your 65mph) with some long(er) GS like turns with my SL skis (WC stock), so it's not that it can't be done. I would say I ski quite ok, and even for me, it's not really best feeling on world doing that. Skis are anything but stable at such speed and at such long turns (or straight line), especially when you are used to GS or SG skis. So personally I think, regardless of what marketing of certain company is trying to sell you, that for such skiing, there are better and more appropriate types of skis, then short SL or SL like skis.My Fisher The Curv GT skis are 168 with 14m radius , My average normal skiing day is speed is 50mph, this season I hit 65mph and did not have any problem handling it at all
