Community opinion of Martial Arts?

[Cheomesh]

So I've got a copy of Martial Arts, and I've given it a quick read through. It looks good, but I am not very experience with the system so I cannot pass any meaningful judgment. It seems to expand on the core mechanics of the game, adding weapon grips and making the basic attack/defense modes do more. The history seems relatively solid, if the Western stuff seems to have gotten a wave into Generia (they didn't even talk much about Johannes Liechtenauer).

As I'm running an Urbanpunk campaign with some east asian influences, I felt it would add a few things, but at the moment all we're using is a single perk - weapon bond - which seems to be a nice little boost for a single point. Oh, and grip mastery, as we're simulating iaijutsu. Quick draw -> Attack (one handed using Bradsword skill) -> switch to two handed grip (or whatnot) -> end turn.

So who's used it and how good is it overall? The cinematic stuff doesn't interest me much, but the "realistic" bits I see myself using a lot. Does it expand the core mechanics well, or is it not so hot? Are there any game breakers I need to be aware of that come out of this book?
