"The PE is an expert level all-mountain park/pipe ski model.
There is no design flaw, nor is there a materials issue. The more expensive P-tex material used on the 05/06 top-sheet is softer than traditional acrylic & urethane mix top-sheets. The harder top-sheet material dulls the edges faster, and has a higher friction quotient when the edge of the opposite ski contacts the top-sheet. The P-tex top-sheet is designed to give (be sacrificed) when whacked by the edge of the opposite ski. If it's getting gouged, it's doing its job. Our pros and testers all prefer the P-tex top-sheet, as it offers higher performance and tends not to 'blow the trick' on a rail or upon landing when the skis are crossed. Additionally, most expert level pipe and park skiers take a wide stance, and do not inadvertently cross their skis; so their edges do not often make contact with the top-sheet or sidewall.
We have had a fair number of skiers (more recreational and learning park and pipe skiers) contact us about this 'issue'. It's really a factor of education about the advantages of the P-tex material in this application and the skill level and/or technique of the skier. Sadly, there were enough 'complaints' and increased material expense that we will be returning to the more durable material in 06/07; which (fortunately) has caused a fury of expert level pipe/park rider purchases of the current model PE. We are now sold out of the coveted 05/06 model."
