i haven't ridden these skis yet so i'll reply back when i do but i've done a bunch of research into them and they are one of the most unique/ interesting skis i've ever seen. first off the sidecut isn't a specific "radius" because its elliptical (meaning that theres a more drawn out straighter part of the edge with a more pronounced tip and tail, like most snowboards) which apparantly makes it much easier to do quick snappy turns in powder, polard even said that he can't straightline in these skis because they are too fun to turn with. also it has a symmetrical flex pattern, meaning the ski flexes the same in the tip as the tail. they are also on the softer side to allow for butters. i think they are going to be such a fun ski to ride in all conditions. as far as the ski being too short you people aren't thinking about the actual width of the ski... 139 110 137 is FAT and should easily be able to support people over 200 lbs. i think you all should stop thinking in certain lengths and start thinking in surface area. i'll get back when i get them myself.
