Replying to Difference Between Line Invaders and Anthems?

Whats the difference between the two?

I know that the anthem is a bit heavier, but how much heavier?

Does the anthem delam easily or is it a more durable ski than the invader?

If so, how fast would it delam if im skiing 90% park hitting jibbs/ kickers?

Which would you recommend?

I live on the east coast so not much powder. Im 5'11' and about 155 pounds.

help would be appreciated.thanks.
