Kung strickly Zildjian speaking pang Rock and Versatility most "commonly" used are New Beats.
If you like them sort of sloshy get wavy bottoms depende na sayo yung Series. Special mention yung Avedis & K Mastersounds.
While yung A custom Mastersound naman medyo too bright for my taste and seem to lack beefiness. It has been my observation that traditional finish hats sound more natural. Pero that's just me.
(ayoko makipag kulitan) I also find the 14" K/Z well adapted for most music it has a Dry stick sound yet it cuts through becoz of the bottom hat. It is very articulate, precise and clean sounding with excelent chick sound when played with the foot. Down side is medyo clangy when played semi open.
I have also heard a lot of people raving about the K Custom HYBRID kaya lang i hav'nt tried them personally so mahirap mag comment based on second hand information. Also since you mentioned pang Rock i'm not sure if it's appicable pero kung pang bahay lang or small venues most if not all of the above should do the trick.
In the End let your ears be the judge as you very well know how a cymbals' sound can vary from cymbal to cymbal even if it's the same model.
BTW Don't forget to bring your current hats when you get new ones this way you'll get a good idea how close or far off they sound in comparison to each other.
"GOOD LUCK & GOD BLESS"
