I picked up a set of 2009-10 Kung Fujas this year, and love them. They have a moderate amount of tip/tail rocker, with camber underfoot.
I can see the benefit of the tip rocker- it certainly helps the ski float well.
But I'm less clear about what the benefit of tail rocker would be. I can come up with the following- are there other benefits?
1. Makes the ski feel shorter on hard snow- I ski 189's, but they ski much shorter on hard snow.
2. Um, more float if I decide to charge Highlands Bowl switch?
