We have been running with no VDS for the last few pairs of big powder skis, we have had no issues, but if you follow any of the big ski company layup videos they always use it... so to error on the safe side i would use it if you got it.... i just dont have any. You said that the big companies post...

Sorry i didn't see that there were newer skis out there...

I am just wondering if the flex of these skis would be equivalent to the flex (and strength) of a good freestyle park ski. I don't see any on this website.
