Rocker-based vs. swallowtail - which is better in pow?

[Schneewurm]

The actual white Burton Fish coming with the S-Rocker-line looks realy great and noble.
This modell which I saw on same shelf like a Nitro Powder (Swallowtail) on a store last Saturday, can be a board of desire for tree-runs.

In fact, the Burton-boy on the stores told me, Burton will turn for 2010/2011 back to cambered boards, but with integrated rocker-lines.

There are now realy a lot different Rockers-shapes on stores. The lines are verry different to others!
Rocker-based boards are for general freestyle and for some-times powder-snowboarding a good choice. Even at higher speed shorter boards with rocker wouln't stick in into snow like cambered boards do. At higher speed on slopes, like for super-pipe or big-air, cambered boards are prefered.
