Replying to Where to mount kartel 98?

title pretty much says it all. I'm using it as a park ski first and foremost (although it will be my ski of choice on non powder days at alta), and have traditionally used symmetrical center mounted park skis. recommended mount is -4.5 from center, which seems a bit too far back for a park ski, but i'm afraid that if i go center it will be too far from the way the ski is supposed to be skied.

any help? in the on3p thread someone said karl rides his at -1, but i have no idea how legit that statement was.
