[logback-user] SLF4J in OSGi ?

Hi, In our company we develop OSGi based applications and use LogService to logging. We use a Log Reader service that writes the logging of all bundles to a group of files. But there are some coworkers that vote to use SLF4J and Logback in a new application because it has a interface with more intuitive methods. but I'm reluctant. I don't see with good yes the use of the static factory method in OSGi. I would appreciate if anyone using Logback on OSGi share any experience and point any advantage of its use instead of the LogService. thanks a lot, John
