b50 ("dacron", actually polyester) can be used on most any stick bow.
you can make a far lighter and faster string using modern hmpe fiber ("fast flight", et al), as long as your bow can handle the modern fiber.
as to dacron being quieter than hmpe, only you can determine that through testing. in many comparison tests, modern hmpe fiber strings are definitely quieter than dacron. particularly those "skinny" hmpe bowstrings.
as always, do your own testing and make up your own opinions and use whatever you think is best. any of these string types will get the job done for all of us.
