OH ...  I love the 13 inch Sabian Fusion Hats ... AA and HH versions. I think they're great and want a pair as well. I can't say I prefer them over a 14 inch pair of hihats; they're just different ... and that's why I like them.

I recently bought a used pair of 13" AA Fusion hats off of Peter Jeffery (Drummer Cafe member). I really like them. Basically they give me a different sound from my 14" A Zildjian rock hats. Can't get more different than those two which is nice. The Sabians have much more high-end projection, an intense attack, and a great "chick." The Zildjians are more full and balanced sounding and are a bit more versatile. But I've been using the Sabians more than the Zildjians live these days. (although I just finished a recording session and decided on the Zildjians.)

Bottom line... I like both, and the Fusion hats are definitely a quality choice if you're looking for higher pitched tonality in your hats. btw, the Fusion 13s are Chad Smith's hats, so if you listen to any RHCP tunes, that's the sound.
