"Personally, I would rather go with the smaller to two options if I was in between a 51 and a 54 (which is exactly the scenario I am in). "
You're relatively long legged and short torso in proportion. The 51 cm might a lot of make sense for you. I tower above you by a whole 3.5 inches with the same inseam, so the larger frame would be more for me, which is what I ride in my P2K.
