who knows anything about them?

I hope this helps...
The radial tune typically has 0.75 to 1.0 degree base bevel on the shovel and tail, and 0.5 under the binding, with a standard 3.0 edge bevel for racing. This allows for easier turn initiation (don't need to be as precise) yet still the quickness of of 0.5 degree base bevel. The radial is being used on both slalom and GS instead of the typical slalom (0.5 base, 3.0 edge) and GS (1.0 base and 3.0 edge) setup.
For base edge maintenance you can use a 1.0 degree tool and polishing/surgical stone, or free hand it.

“During the winter season I go skiing 3 to 4 times per week to test
different types of our rental fleet. Since we have had our MONTANA
Saphir with the radial tuning I can feel a much better turning capacity
together with easier handling. I can actually feel my skis and they
react like my race skis used to and those were prepared elaborately
by hand by my ski man according to my needs. Because of the very
positive feedbacks all our skis and boards are prepared with radial
tuning. It is an investment to the satisfaction of our clients and it has
already paid off.”
Andrea Zinsli: Former Swiss Worldcup Slalom athlete
“I have tested the Radial Tuning at large and it is awesome. The
radial tuned skis are extremely smooth to ride, steering is easy and
safe. The edge grip, in particular under the bindings is fantastic.
It is easy to control the outer edge, all in all an outright quiet and
stable handling is guaranteed.”
Mike von Grünigen: Former Worldcup champion
"One of my tasks in the race department, among marketing,
developing and testing material is the continuous search of new
technologies. In the further development of our products I was able
to know Montana’s Radial Tuning and I have done a lot of tests on
different models, all prepared with Radial Tuning. The skis are
extremely good to turn, react more accurate and receive a balanced
and fluent dynamic. The results of the tests have completely
convinced me: all my test and racing skis are going to be prepared
with Radial Tuning from now on.”
