Are you calling Eric Hjorleifson a line backer?
Heres a break down of the EHP:
193cm: no camber, early rise tip, excellent in pow, not responsive on hard snow. perfect for big fall lines and consistent pow. i.e. cat, heli, sledding, etc. NOT A TWIN.
190cm: twin tip, normal camber, stiff, excellent big mountain resort ski. Like the Armada ANT but heavier. It also has a stiffer tail.
186cm: Same construction as the 193cm, little to no camber, early rise tip and a slender tail. Definitely more resort friendly then the 193cm, it still isnt a true twin. Great in deep snow, easy to turn, good for technical lines, with lots of obsticles to avoid. mediocre on hard pack.
