Replying to Where to mount?

I got a pair of seth vicious this season and i had them mounted 1.5cm up from the midsole. I figured that I already had a pair of park skis mounted center so why not have a ski more traditionally mounted for more all mountain skiing. However I broke them this weekend and K2 is sending me a knew pair and I cant decide whether to do the same thing or just to mount them center. I liked the rear mounted set-up.. but it just didnt feel good skiing fakie or spinning... Any advice?
