Tons of players use Bay Ligatures: Sinta, Lulloff, Forger, McAllister, Taimur Sullivan, Cliff Leamon, Miles Osland.... and the list goes on.
The thing you have to be careful of is that they are extremely fragile! They can break and bend on you in a second.
Other ligs that I've seen players use; Vandoren Optimum, Francois Louis "Ultimate" ligature, and the Eddie Daniels Rovner.
Vandoren also just came out with a leather ligature. Design is very similiar to a Rovner, but there is a contact plate at the bottom...plus it's leather, not a cheap plastic. Happy Ligature Hunting!
