Powell Peralta Flight Decks are thinner, more stable and therefore more durable than normal decks.
The epoxy-interspersed, fiber-reinforced structure of the flight deck is extremely break-proof and gives you "eternal pop" that does not fade when your deck slowly wears out.
Flight decks last many times longer than a 7-ply maple deck, which makes them cheaper if your deck breaks frequently, despite the high price.
