I've put well over 10,000 miles on the Dura-Ace 7900 crankset and more than 15,000 miles on an FSA K-Force (Light) crankset.
Dura-Ace 7900 will be better than FSA K-Force. FSA K-Force "Light" is more on par with the Dura-Ace crankset. I like the fact you get ceramic bearings with the K-Force Light. Dura-Ace 7900 will be a little stiffer, but also around 100 grams heavier as well. I'd recommend going to a 172.5 instead of 175.
