Well as long as this old thread is back from the dead.
I like my K Customs too. I had a 20 KC that I bought used in '93 or '94. I should have never sold it.
I have a couple of 18" crashes. The KC Fast crash and the Session crash. Both have great sounds.
I have been using regularly a 22" KC High Definition ride that I got back in '04. I went up to the Zildjian factory, did a little tour, and they let me try a bunch of these rides that they had recently made. This was Terri Lyne Carrington's signature ride when it first came out and I was intriqued.
Wide spiral lathing, raw bell, big and round hammering. Very different from anything I was used to. At first, I was smitten with the darker smoky tone, the dryness, the controlled spread and that the stick feel is a lot like the Ping ride I was so used to playing. So I picked one and they sent it to my local GC and I bought it. Then I started playing it in a band context and I was baffled. It didn't work so well. The darker stick tone got lost in the mix a bit. What it had in definition didn't sound overall as good without more wash behind it. Not a very useful crash sound for most of the Blues, Funk and R&B we were doing. I rotated it out for a while and went back to the A sounds that seemed more familiar to me. The Ping, the Medium, the Sweet.
A few years after TLC redesigned the ride in 2008 to be thinner and more crashable, I got curious. Eventually a Guitar Center near me had one in stock and I brought my KCHD and tried it side by side to the new one. I wasn't thrilled. That trend for more crashable rides turned the new incarnation of this ride into a dud.
Then I was listening to one of my favorite albums by Hadden Sayers. His live album, Swingin' from the Fabulous Satellite had this great ride cymbal sound that just spoke to me as being the almost quintessential ride sound for Blues and Rock. I was convinced it was an old A or maybe even a K Heavy. I emailed the drummer, Eric "Magic Baby" Hansen and a week or so later he emailed me back and said that it was in fact a 20" Sabian Leopard Ride. He also said that he had had a really fantastic sound engineer on that album.
This link is to a fairly decent file to hear this ride sound.

Anybody's who has ever played that ride will tell you that it's heavy, dark, dry and a bit of a beast. The 22" version even more so. I started listening to some videos by Billy Ward, Tommy Igoe, Al Evans from SoulLive and mycymbal.com to hear the K Custom HD since they all have played this ride.
On mycymbal.com, the ride sound was like I hear it underneath me on my kit. A little too dark, too dry, a bit gongy when shanking the bow. All the players' recording sounded great. A bit brighter, defined stick prominent in the mix and a cushiony wash instead of gong tone.
Then my friend Clay played my kit with a set of 2Bs and I sat about 30 feet in front in our rehearsal room and he beat the snot out of that ride for about 30 minutes. I had a pencil condenser mic under it and recorded it to a Zoom R16. Unbelievable the difference in sound.
So I really learned something when it comes to the difference in recorded sounds and FOH sounds in relation to my sound perception of the kit underneath me.
Now I always take the extra time and trouble to mic up my ride so that it's right up there in the PA. I also always bring my own mic clamp so that I can use the high hat mic for the ride if I have to fore go one for the other.
Now I love my K Custom High Definition ride. It's a 6 lb. slab of heaven that is everything my Ping ride can never be. As long as I use at least a wood tip 5B it sounds fantastic. Nylon tips brighten it up nicely for Rock. It doesn't want to be played like a 4 or 5 lb. ride.
There are some really great rides in the K Custom line. I've played them all and I like the 20 K Custom ride, the 21 K Hybrid Ride and the 22" K Custom ride the best after my HD ride.
I also really like that Sabian HH RBDR. I played one of those last summer on another drummer's kit and it had the same qualities that I look for in a ride.
I think one of other members, Wy Yung, has this ride. I haven't met or dialogued with any other players that have this ride. Wy, if you're out there, how about a cymbal review on the 22KCHD ride.
