I said 5, because I *think* the order is:
Splash, Hi hat, ride, crash
…I will probably be proven wrong.
EDIT: I changed my answer. I don’t know WHY I didn’t see such a small hole on the first cymbal. I was focused more on what I thought were the “tiny hammering marks” that I’ve seen on some K splashes at the local Guitar Center, as well as the size and location of the “K” ink. That second cymbal very well could be a 12” or even 10” splash.
