trust me it really affects it a lot if you know how to carve a ski properly. i went for dead center of the ski on my karmas, which made them about 7 ish cm further forward than even the park setting and they skied like shit. i had to lean back into my boots so hard just to get the edges to set in it was ridiculous. plus they really didnt ski very well switch either, which i was very surprised by. i took them in, got them remounted in between the recomended line for all mountain and freestyle and they absolutely kill it. they are far more stable, i can actually put my weight into the front of my boots like you are supposed to and the edges will set in. before when they were centered and i would put my weight in the front of my boots like i would when i would carve the tails would lift off the ground so they didnt carve. also, with them mounted where they are now they ski amazingly well switch.
so to the creator, if you actually enjoy carving your skis and like having the slightest bit of control, as well as keeping the tails on the snow when you are skiing then absolutely do not get center mount. i mean sure going in front of recommended is fine, but do not do it to extreme lengths like i did unless you like being out of control all the time. i certainly found that out the hard way.
