All of the rocker/reverse-camber/early rise terms are used differently by different companies. The key is to know what each company means, and what that means for the ski.
For us, rocker means there is an actual radius in the camber profile. We don't differentiate between reverse camber and full rocker (aka the Renegade). The YLEs, EHPs and the CRJs have tip and tail rocker and also camber underfoot.
We take early rise to mean that the camber radius is flat, so when you flex the ski, it splays open a little, but if you were to lay it up against a wall you'd see it lie flat.
Also, having skis with too much rocker causes you to plow the snow instead of ski through it. That's bad generally. We like longer, less extreme rocker to allow you to plane across the snow easily. That's the same idea Line is using this year in the Opuses.
