The original 05/06 invaders with the pink topsheet had serious de-lam problems. Line fixed it for the 06/07 model.
I had the 06/07 model and have skied the 07/08 model, they're exactly the same, just a different graphic.
Invaders are great skis no doubt for $299, they're definitely worth it. The only problem is the base is so fucking hard because they wanted it durable. It makes wax just bead up on top of the base instead of getting into the pores, which makes them slow as balls. Especially after good mid-season use. I had to wax almost every night before I went skiing eventually.
I still got like 35-40 days out of my Invaders, they aren't completely dead but just super slow and really floppy. For $299 I couldn't find a better ski though....
