nope. core center is the forward-most recommend mounting spot, true center is when the the midsole of your boot is in the exact center of the ski. depending on the ski core center can be pretty close to true or a ways back.
that's plus 7 from traditional, which on k2s is hellla far back. If you're mountin them for pretty much all park just do true center, if you want some all mountain do like 3cm back from true.
true center is exactly center of the ski, do it only if you ride park like all day. Core center on fugitives is still pretty far back. Made that mistake, they don't ride park as well on true center.
