I recommend these little Charley strong friendly, accurate and aesthetically successful.
Update 20/02/2011: After a year of little use, I recommend these for charley funk groove.
They are really intended rock (lower cymbal very thick). Regardless of medium, too late and too metal for me anyway. I sell on this site elsewhere.
A Custom series is high quality but preference for rock or metal. To jazz or funk, search for K or K custom to be softer in the end and midrange.
