first off, what will u be using these skis for?
second which skis are u considering?
yes longer skis are harder to spin but not much difference with lower swing weight in new freestyle skis.
if you feel you can control a longer ski go for it! its better for backcountry and pow...
either way you will get used to what you get and learn to appreciate it...
In my opinion the length of your skis should be anywhere from your nose to 2 -3 inches above your head...
