get em dead center...or recommended either way it is not a big deal because the sidecut difference will be so minimal there will reallly be no feedback to your skiing. Really the question is how much tail you want. Either way the difference of dead center and recommended will be minimal. For me l would just get them center because if it were me it would bother me just knowing that they weren't, at least that is what happened when I got my first twins mounted at recommended vs center
