Help to choose a crash

Hi everyone !

I want to buy a new crash for my drum set,

my current cymbals are :

( all zildjian )

- K 15 dark crash

- k 14 Hihat dark

- a ride sweet 21"

- a 8" k splash



I would like recommendations on what to buy that would fit my current setup,

I have been thinking of the 17 k dark or the Constantinople 17 k, because I heard that 17" generally go well with 15"



I also thought of mixing brands but I have no experience with the other ones so I don't know how they would blend.



Any help is very appreciated !
