which ever you prefer would be fine.
those fujis have higher than normal bottom bracket. 45mm drop instead of 50-55mm. so that should give more than enough pedal clearance with 170 if you want to ride reeeaaalllly slowly.
And i'm pretty sure many of the world class endurance riders use 170mm now, unless they are short.
One thing high bottom bracket does is higher centre of G, which affect stability of the bike a bit. 170mm would compensate that a bit, I would imagine.
