Define better rail skis?
The afterbang will have a slightly lower wing weight because of it's symmetry, but the LTE will have a lower total weight. The afterbang is slightly softer, but the LTE will carve a bit better.
I had the Phil Larose Pro (the LTE before Phil left Liberty) and the Afterbang in the same season, had the Afterbangs for most of the season, broke them, got the Libertys, skied them for a month and learned twice as many rail tricks on them than I did all season on the Afterbangs...take that for what you will, it could have just been a good month for me, it could be that the skis worked better for me. Either way, I came away from that season disliking the Afterbangs and liking the Libertys.
