Akshally, I'd say the two things are more or less exclusive. Frelists are mostly relevant to block contention due to INSERT (and maybe DELETE?) activity. While INITRANS is mostly relevant for block contention due to UPDATE. This is why it is important when talking about a database with "lots of updates" to be specific and explain what kind of "update".
