I really liked the Wounded Lion scenario. It's nice to see 'storyline' scenarios - one of my favourite campaigns for B5 ACTA was the Masked Malice scenario, which used the same ships in an end-to-end story.
In fact, you could probably convert it over very easily; initial scenario is a federation frigate of some class being hunted in an asteroid belt by a D7C command battlecruiser rather than the strike carrier/white star of the original. Most of the rest of the scenarios can be adapted as well - although the 'not yet at war' bit with the centauri/minbari etc from the second half could be dropped.
