I'm in the market for a new crankset, and I want to try to get something really light. I don't push a huge gear, so most cranks are stiff enough for me. What do you recommend?

Truvativ Omnium
FSA Carbon Track
Sugino 75
Sugino Grand Mighty
Campagnolo Record
Dura-Ace 7600
Dura-Ace 7710

Which of these is the lightest? Any other suggestions? I'm leaning toward the 7600.

Thanks a lot.
