I think the stock type spoiler looks the best. Nice choice! I know exactly the feeling you had drilling them holes. Two days after I got my PT I put on a old Mopar Performance license plate ring that I used to have on my Super Bee. I had to drill two extra holes for it. You get the "I can't believe I'm doing this to my new car" feeling. In a year or two, we won't think twice about doing it.
