Replying to East Coast ON3P FR or Prester

HI,

I ride a 176 klint pipestar which is cambered. I was looking into the Filthy riches and was wondering if you guys could help me out with a choice.

How well would Filthy's hold on icy days? Would I be regretting buying a rocker ski?

I ride groomers and park, hitting mostly rails rarely seeing natural snow.

should i wait to buy presters which is a cambered ski or would i enjoy the FR

should i just stick to a cambered ski?

What size FR should i get if I'm used to a 176 camber, 181 or 176? i am 5'11 160

If not any of these skis then whichhhhhh should i look into

Thanks
