Yeah, read that other Line vs. Bro thread, I posted almost the same thing there. But here goes. The Mantra is stiffer damper, and move like a race ski to me. It can be driven pretty fast without feeling sketchy, and when mounted back a bit really doesn't have a speed limit in my opinion.
The Line is turny, poppy, light, and fun. I had one of my best days this year on a pair of 100's. At 186 with a bigger twin than the Mantra, the ski is basically the same in size as the 184 Mantra. However, for me the float in powder was night and day. I could got after it with the Lines in untracked as fast as I wanted without worrying about tip dive. The Mantra on the other hand simply did not float for me without giving it a lot of attention, or even going to a more old school "up and down" active kind of turn. This even after going to a 1.5cm back mounting position. In trees and soft bumps the Line was super playful and fun as hell. The Mantra is fine too, just more work and more tiring. In hard bumps I strongly preferred the Mantra as the line was a little too wide and got pushed around a bit. On groomers both are fun. On soft western snow the Line was great. But the second the snow got a little hard the Mantra won hands down. The Line's tip deflected more and you couldn't really drive it like the Mantra. The Mantra is also more at home in variable snow. It isn't a true "big mountain" bomber like Legends or Squads. However, it is solid and more similarities to such skis than the Lines. (again, especially with a rear mounting position). I dropped into a steep sketchy line with the Lines that turned out to be 3 inches of soft with ice and death cookies underneath. I was quickly on my ass. However, on the Mantras I could have charged right through it. Straightlining I would take the Mantra over the Line hands down, no question.
In conclusion, if you want the most playful, funniest, lightest ski that is best in powder get the Line. If you want a more solid feeling ski that will be serviceable in powder, but do really well on hard snow get the Mantra. It won't float the same as the Line, but it will give you more hard and variable snow flexibility.

"I demoed the Davenport 2 weeks ago, I really liked them a lot... the blue sidewalls and tip really looked great with my pants. I also tried the '11 MX98, they didn't look as good with my outfit. If you have blue pants or maybe some Lange race boots I recommend you check them out."
