Replying to Strange Ski Question: Rocker

Right now, I ride an old pair of Ar6 that I have rockered. This is just by extreme use and such. Sadly, they are on their way out, so its time for new skis. I loved my rockered Ar6s.

My question is: should I buy skis with rocker or should I buy cambered skis and let them rocker over time? I plan on having these skis for three or four seasons.
Also, If I buy a rockered ski, will it eventually lose all camber or will it stay with the original amount of rocker?

Please help NS, this will greatly decide my ski decision.
