If I may throw my 2 cents in........
So many factors effect how the stick sounds on the cymbal. Tip type (Nylon/Wood), tip shape, taper, length, virtually every part of the stick is a factor. Also, the condition of the sticks comes into play. A worn wood tip will sound much more legato and subtle than a new wooden tip of the same model.
As others have said, different woods make different cymbal sounds. I really like using maple sticks for jazz. They have a lighter and softer sound, and really change the color of a cymbal, especially if it's a thinner one.
If you want really light sounds of your cymbal, I suggest you check out Bopworks drum sticks (www.bopworks.net). They are new sticks but made to the specifications of older sticks (40's, 50's and 60's). The Birdland model is their flagship model. That stick will make your cymbals sound way different, but a very good and welcome different! Also, the Vic Firth AJ6's are good....it's impossible to get really loud on your ride with that stick. Similarly, the Pro Mark MJZ-7 is even better than the AJ6. They are identical sticks, but the MJZ-7 is made of maple, so it's even more subtle. AJ6 and MJZ-7 also have fantastic rebound off the cymbal. Those are my go to sticks when someone calls "Seven Steps To Heaven"!
When it comes to actually picking cymbals, I usually bring a variety of sticks with me with varying tapers, tip shapes, etc. You can usually get several different cymbals for the price of one!
Another thing I like to do is hit the cymbal with my hand and fingers, especially riveted models. With a hand stroke, all you hear are the rivets. If it sounds good that way (no stick to influence or distort the sound-riveted or not), I know it will sound good with any stick I choose.
