Replying to Durability of 07 invaders compared to 05-06 invaders.

i know that the invaders had problems last year and they basically kinda sucked as far as construction is concerned. Does anybody know if they got the kinks worked out this year, are they delaming after 1 week of use or are they beefier this year? also how do the edges hold up on rails, my old skogens were basically indestructible on rails im just curious how these might hold up. fyi i already ordered a pair of invadrs this year, i just want to know what to expect
