My standard set of cymbals these days is a 20" Instanbul Agop Signature Series ride and a 18" Sabian HH Vanguard crash-ride. I got the 20” Agop ride from Tony at CymbalsOnly.com. It’s thin and light, so not loud, and partially lathed top and bottom to give a warm, dark, soft sound, with good stick definition and not too much wash. I think these are unique to Tony's shop and I would recommend him to anyone looking for cymbals online. I have also found his cymbal recordings/playing to be to be very accurate. I got the 18” Vanguard from myCymbal.com (Memphis Drum Shop). It’s also thin, fully lathed, has a great dynamic range, and sounds and feels great. For additional color I have a 16" partially lathed China cymbal that I picked up in some tiny music shop in Shanghai a number of years ago - the perfect China-sounding cymbal, and I often use a 20" Bosphorous Masters Series ride cymbal as a second ride, to which I installed a single rivet for mild sizzle sound. These span a range of nicely matched pitches. Of course, I have many more cymbals, which I pull out in different playing situations, and lately I’ve been stacking an 8” UFIP splash cymbal on my 18” Vanguard crash-rice to make it sound a little trashier.
I generally use three pairs of hi-hats, depending on my playing situation. These days, my go-to pair for light jazz is a 14" bottom cymbal from an old pair of Zildjian New Beat hi-hats I’ve had for 40 years, paired with a 14" Sabian AAX X-Plosian Fast Crash on top. Very soft and dry, with beautiful tone, mostly due to the top cymbal. When I need more volume, I go to a pair of partially lathed 15” Bosphorous Masters Series hi-hats that I got from Tony, and to which I’ve installed two rivets in the bottom cymbal for a little extra sustain when I open them up. Although these cymbals are bigger, they have a soft sound that is not too metallic and still great for jazz or heavier styles. When I need something cutting, with a definite "chick" sound, say for a big band, I go to a pair of 13.25" Zildjian Custom K Hybrid cymbals. They are very crisp and responsive, but sound a bit metallic to my ear.
