from what i have heard from ppl who have demo'ed the invaders, they are sick skis for the park with really nice "butter zones" but those zones really effect your groomed runs and your skiing outside the park. the invader sounds like a pure park ski but if you want an all around sick ski, the PEs would be a better choise. thePE was fattened in the waist, so it can really attack anything, from the light pow to the groomers. but the PE was softened up so it will be a sick park ski also. both graphics i think are awesome and though ppl say that graphics don't matter, we all know that they are an influential part of the decision making process. both are pretty cheap too, so its not really a matter of price either. i personally think you should go with a PE, esp if it is gonna be your only ski. but that is only this humble man's opinion.
