I have a pair of the old ones, they were a pretty fun ski, camber with tip rocker, they were pretty flexible in the nose and tail and were fun to play around in. They didn’t last long because the tips and tails all delamed in a few weeks badly but it was a fun ski.
I’ve skied the helix 98 as well as the origin 96 and 106. They were all ok skis, nothing special. The origin 106s were wayyy too soft in the nose and all three models just felt kind of cheap and chattery on my feet. Helix’s did have a good amount of pop though
