The Rovner Platinum. First off, it ain't actual platinum, so don't start melting them down and building your life savings from those lumps of metal. They're an alloy.
But hey, it's the first ligature from Rovner that doesn't contain fabric. I gave this ligature a try, and I found that it is pretty similar to the Vandoren optimum, but a little darker. It's also got a bit of "zing" in it in the upper clarion. Your mileage may vary, but it's definitely worth a try.
One hidden benefit of this ligature is its reed-gripping capabilities; if you use synthetic reeds, you know that you've got to take the reed off before taking your mouthpiece off, because otherwise you'll have a reed-mouthpiece-ligature salad in your hands. The Rovner Platinum will grip the reed and mouthpiece such that you can actually take off your mouthpiece (or put it on) without the ligature sliding all over the place, and scratching your mouthpiece.
