all problems with invaders are from the past years' models...i have skied on 06 invaders, 07 invaders, and now 08s, the 06s were shit, so i bought some 07s..they were a little better, but still delaminated.  I got a pair of 08s from a warrantee, and i have skied them for the whole season without any delam, and i have never heard of one breaking.....this years invaders are baller skis, and they are close to bulletproof
