Ph1 needs the cup spoiler. The standard is a bit small and doesn't really have a decent shape but the trophy spoiler is a bit too pointy for the curvy ph1 looks in my opinion.
Few pics of my old ph1 with a cup spoiler. I thought it looks the best out of them all and the little flick at the end complemented the ph1 shape.
