i have just demoed a pair of 1080 foil and was quite impressed. i do not know if it has a foam core or what not(wouldn't be surprised if it does have a foam core), i will just review on the ride of the sticks.
they are very similar to the pocket rocket in dimension wise but i find them eaiser to carve. they are quite light and have a, i say a medium flex. i can carve gs turns without much effort, and it holds itself pretty well on ice. i live in the east so i cannot test their performance on pow.
the ski are quite easy to spin on, good balance and i think the light weight make a good contribution to that as appose to my dynastar candide(which still rocks). i did not test them out on rail since they are demo skis, but judging from the wide platform it should be very stable.
in conclusion, if i have the money i will buy a pair cause they are quite fun to ride on and i might go out west next year. i have a pair of dynastar candide and for sure it will not be any good to me in pow. it's hard to say if i like the foil more than the candide or vise versa since they are completely different ski(freestyle mogule vs. freestyle backcountry/all mountain).
