Unlike my unfavorable review of the 16" Fast Crash from this series; the A Customs- I really like the A Custom's 18" Fast Crash.
What I like most about the A Custom line-up is their versatile sound, being very modern sounding but traditional enough for more than just rock. The 18" Fast Crash is no exception, as it has a very shimmery modern sound, and is mellow enough to be utilized in a wide variety of gigs. Its a good cymbal for guys who play in different types of bands and need a good "go-to" cymbal for different styles.
The 18" Fast Crash has a great sustain thats not wimpy (unlike the 16" version) so it can be played like crash/ride. It has the density to stand up to it and not flop around like a fish. And, like the name implies; the crash is "fast" so its sounds more punchy and punctuated than most 18" crashes. All of these characteristics blend together perfectly, in my opinion, and this cymbal is explosive and punctuated, dark, modern and shimmery, and with great sustain, and its still versatile enough to play this in a modern rock band all the way down to jazz. Its not as complex as some players might demand, but it does have great musicality and sensitivity to pull off different styles well.
This is one of my favorite crashes ever, other than a few that Paiste has to offer. Its not bad for the price considering the use you would get out of it. It wouldnt replace my standard 18" crash in my setup, but it would pair up with it as a replacement for my 16". Thats how "fast" of a crash it is, you can replace your 16" with it for a fuller sound but not give up the punctuation or explosiveness you expect from a smaller crash!

You will love this cymbal.

I did not use this cymbal long, as it just didn't jive with my tastes and expectations. It might for you, though. The 16" Fast Crash is pretty typical and in line with the rest of the A Custom series, but this particular cymbal is just not of use to how I play and what I prefer in a crash cymbal.

What I liked about this cymbal is its shimmery blast of sound that hits you in milliseconds of hitting the cymbal. They didn't call it a Fast Crash for nothing.

What I did NOT like about it was that I found it a bit thin and anemic sounding for a 16" cymbal. It had the sustain of a 16" or larger, but the wimpiness of a 14" or 15" crash. It lacked fullness. Even its sustain was just the tone lingering, and not a full reverberation of the cymbal. It is probably due to the thin-ness of the cymbal, its fairly lightweight. It seems like to achieve the "fast" crash that this cymbal is named for, it had to lose any fullness or deep sustain that it could have otherwise had had it been a more substantial cymbal. Its a trade-off for sure, and a trade-off I'd rather not make.

So in my opinion, I would never use this cymbal in a rock band, even though much of the A Custom line-up is perfect for everything from mellow rock to aggressive rock music. I would maybe check out the 14" or 15" Fast Crashes as a more splashy cymbal in the future but the 16" has no place on my kit. I could reccomend trying out this cymbal to anyone who plays more modern jazz or fusion type playing. They might appreciate the mellow sustain and punctuated "fast" crash sound of this cymbal.

I owned my 16" AAX Stage Crash for a couple years before I sold it off to another drummer.
The sound quality of the cymbal changed dramatically to my ears over the time owned it. I remember buying it and thinking it sounded great, to eventually cringing enough that I replaced it with a different brand of cymbal. I don't know if it was my partially my taste that changed or refined with time, or if it was completely the cymbal's sound degrading with time.

The finish on my AAX started out brilliant and shiny, and dulled dramatically with time, while staying set up in an air-conditioned home and only occasionally being handled to gig out. It seems like just exposure to air, natural light, and skin oils ruined turned the original brilliant finish to a dull discolored appearance, and dulled the sound as well in just a couple short years.

My AAX stage crash was punchy with minimal sustain, and fairly balanced in tone and not too bright. It was perfect for the pop punk rock band I played in as a teenager, ideal for quick syncopated crashes where it could cut through. Later as the finish dulled, it started to lose its glassy high frequencies and took on a more shril brassy sound that made me cringe.

One thing I didn't like was its light weight, as a result playing overly heavy or riding the crash were out- it flopped around like a fish. It was more like an oversized splash cymbal than a hardy crash. I had to rely on my other crash for that type of effect.

I finally grew disgruntled with this cymbal and sold it for 20 bucks to a younger drummer in need. I had only spent $80 on it but until you got into the uber expensive Hand Hammered line I thought this was the best Sabian had to offer and would serve me better than it did. I ended up going with Paiste from there on out and never looked back.

If Sabian has upped the quality of their AAX line in the last 10 years then maybe they are worth checking out, after all I did enjoy mine for a while befopre it went south on me. If finances allow it (and they did for me) I would go for the hand hammered line or not buy Sabian at all.

I owned my Paiste 2002 18" crash for a couple of years before sadly parting with it. I like the lower overtones and the deep wash it gave me, which were mostly due to its 18" size. I started to stray away from smaller crashes and splashes due to the weak wash or sustain and harsh high frequencies, and ended up playing only a 18" crash and 22" ride form Paiste's 2002 series. The two cymbals blended perfectly together for playing in an heavy hitting indie rock band.
I like the finish on the 2002, its not very brilliant but it held up really well for years even though I was constantly setting up and breaking down my set, and never even wiped the cymbals down from hand oils and fingerprints. This had ruined the finish and even dulled the sound on a Sabian AAX crash I had previously.
Another thing I liked about this cymbal, was that it was fairly loud, not in a harsh way like the RUDE series but in a way that filled a room and still cut through a band. I would say that the entire 2002 series is probably sonically somewhere between the RUDE series and the ultra expensive Signature series. They have a bit of the power, projection, and volume of the RUDE series, though more musical and sensitive like the Signatures. They lack some of the complexity and refined tone of the Signatures though, to be a more powerful cymbal that would stand up better for heavier rock music.
My 18" crash proved very durable as it served me in playing heavy rock music. My technique involves setting the cymbals low and flat and being struck most on the edges instead of the face, so the edges received a lot of abuse from the sticks wihtout ever being dinged, dented, or warped. I think it has a lot to do with the thickness of the cymbal, and yet again is another reason why I was better off with 2002's than Signatures which can veer to the thinner side.
My Paiste cymbals were the most expensive cymbals I had ever bought, but I had become disatisfied with zildjians sound, and Sabian's quality of anything below the Hand-Hammered line which was too pricey for me. I believe I paid almost $170 for the 18" crash, more than I had ever paid for a crash, but still more affordable than had I bought Sabian Hand Hammered or Paiste Signature.
If I had to buy another setup all over again, I would try and buy Paiste Signatures if I could afford it because I would enjoy the complexity and brilliance, but for what I was playing when I owned the 2002's- they were perfect. I followed good adivce from fellow drummers in the same style of music, and played a ton of cymbals before buying them, and they stood up to the abuse I gave them.
