Spice & Wolf subs

I'm thinking of starting watch this. Which group has the least retarded subs? I've heard complaints that some groups pulls stuff out of their ass for this series.

BSS is fine, haven't sampled Infinite Zero's though. Horo's speaking in ancient Japanese (think speaking in Yoda's style for reference), so it's supposed to be a bit odd.

But hey, I'd be a bit irritated if the subtitlers put in "Thy, thine, ist, art, thou" because it would require me to... well... think.
