But obviously I haven't looked into this very much.
As I understand it...
The front of the Early-Rise ski could be called 'front rocker' and a ski with both the tip and tail rising up could be called 'double rocker'. Both versions could still have camber in the mid section. A ski with no camber might be called 'flat' (not sure if the term 'rocker' applies there). A ski with reverse camber might be called 'fully rockered'. This, based on what I've heard and read for the last season or so.
As to WC Racing on such skis - I don't see it happening.
Early rise targets tip-lift in soft snow more than anything else. A second benefit is the shorter continuous contact base when not tipped much (easier pivoting and skidding) but that only applies on firm surfaces. Sure, such skis can carve but I think they'd be a disaster at high speeds on ice since that Big Floppy Tip would be bounding all over the place. Might even slap the Racer in the face.
Tips flopping around wildly already happens on downhill skis but they generally don't cut it close to every gate. What if that Big Tip flops the wrong way
just as an SL Racer's tips reach the gate? And how about the consistency of tip engagement if that tip is flopping around wildly on ice?
In faster events I'd think a big problem would also be the wind-resistance profile of that tip. Certainly slower (can you say Hole-Ski? How about Really Big Hole Ski?
) And instead of 'lift' in the snow, what happens if that tip provides considerable 'lift' due to airflow at high speed?
I just don't see a migration happening into the WC. Maybe in beer leagues at slower speeds and on mushy courses though. Certainly would practical racing in spring slush during the Bikini/Shorts Race at Crystal.
