Probably about what they're on now, somewhere around 30m, assuming setting trends are similar.Eliminate the 30m regulation, what would be the fastest ski for WCers?
In the >21m and >27m eras, the top men were typically on something with an actual TR of 29-32m. No reason to think that would change.
Would it change for women? Maybe a bit? I'm not sure what the women were actually skiing in the >21m and >23m eras. Maybe somebody who does can chime in. But I think the radius would stay around where it is now (sort of 27-32m); it's workable. Still work to be done on layup, etc. IMO.
I believe @ScotsSkier and I (and some others) had a discussion about this a year or two ago. Maybe somebody can dig that up.
TBH, flex pattern is more important than the radius of the ski, but ... most "normal" people don't really get a choice in flex patterns
