ok, if you hold the 2 skis next to each other, heres the big differences:
extruded base- shitty and slow
line sidecut, stable, but not too turnny
wider tail, better switch
a little wider overall.
not as light as 4frnts
still pretty light
way better base
mpre pintailed with alot of sidecut- very, very stable.
stiff as shit
ultra light- about the same as 1260s
way better built than either lines. these things are art
not as park oriented, the sidecut will make you general all mountain riding way more enjoyable, but they wont be as useful switch in powder, or as stable skiing switch.
i would say 4frnts, but if your ridding style fits the mo ships, go with the TIs. the flites are made to be a really really cheap powder ski. the good base and stiffnes is worth the extra cash
opps, that was free advertising.
