Honestly, you're going to have to go to the store and try out some plates. You have Zildjians, so you're dealing with high levels of inconsistency. Projections equal a full bodied and strong crash, while fast equals a quick and (somewhat) splashy crash. It depends on your flavor that you're looking for. In other words, if you're using the word compliment as in matchnig the sound (without sounding the same), you would have to get a cymbal that's close to the weight (and maybe size, if you're going in that general direction) of the crash that you are trying to pair it up with.
I (or we) could give you the name and series ot cymbals, but again, if you go to the store, it (probably) won't sound good to your ears - for me, most of the ones that I hear in stores are horrible sounding. That's just the nature of the beast when you're dealing with Zildjians.
To sum it up, you're going to have to go to the store and try out some plates to see what you like. Don't forget to bring the crash with you.
