I can't think ok anyone I know who fits a 54cm bike that runs 170mm cranks.
You find it more efficient? I'm curious about your move to it, so probably should have been more explicit with my comment.
I run 170mm cranks on all my bikes. I ride a 54cm, and I have long legs. I found I can spin a higher cadence better with the 170's. I've tried 172.5, and 175 as well. For me they work better, and help me to spin instead of hammer. I don't think I will ever switch back to larger cranks.
As for the OP's S5. Looks good. Aero and light is always a good combination. Keep up the good work.
