Ok man, i had this same problem when i got my skis center mounted, and i was like "WOW they forward mounted them!". But then, i figured out how skis were mounted and discovered why my tails looked longer than my tips. When you "center mount" you are mounting the center of your BOOT on the center of the ski, and it just happenes there is more length on the toe piece too the boot than the heel piece is to the heel, making your tails seeming longer. So very though they look forward, they are center, shops arnt that stupid to mount forward.
