i too was amazed by the Star Destroyer. It outflew my Pro Orcs even though there was a left to right tailwind and the Pro Orcs are my prefered disc for D. It is also incredibly fast -- it gets small quick!
normally i don't like discs this stable, but i am liking this disc!
great name too -- wasn't that the name of one of the best Led Zeppelin bootleg LPs(?)
