I'm 6'2 and I rode 182 halo's this season, and they do ride a bit shorter, however for a centermounted park ski, i didn't find them that bad. The past 2 skis i've ridden were 178 jib nas (which I hated) and 181 JO pros (wood core ones, which I liked). The halo's were a nice inbetween, they could still carve unlike the jib nas which were hindered by being fully rockered and magnetraction, but the rocker gave them way more play than a traditional cambered ski
durability wise they've been good so far, but i only put probably 30 days on them this season, which is pretty low. I also found them super light, but that is comparing to the two battleships I rode previously
the sidecut does take some getting used to, but honestly once youre on it you'll never notice the difference
the one thing I did notice is that for a light ski, it was fairly stiff which I'm a fan of. From what I understand the FR is more the on medium flex side of things, which for you at 160 might be more appropriate depending on how stiff you like your skis
overall I found halos to be a great skis, unfortunately I can't give them the full run down against the FR
