Where to mount Head J.O Pros? Need to know until tomorrow

[1990]

I scored myself some new Head J.O. Pros and now i am thinking about the mounting point.
I am a good skier, ski since I am 3 years old and also raced a good amount.
My park skills are average. I'll do spins up to a 7, front and backflips, flatspins, 270 offs and switch ups.
I also jib a lot on the piste and stuff.
Park and Piste would be 50/50 for this ski. For Powder I'll use Bents.

Should I center mount them? or take the FS mark on the ski?

Thanks
