As long as we're on the subject of cranks (kinda), I've been thinking about finally changing out my bent Miche set.

What's your Honest Dude's Opinion on S300s? I'm sure the arms are stiff enough for a street bike, but how about chainring roundness, chainring bolts (steel, according to your site?), BB, etc. Also, what's installation like for those GXP jawns? I've never handled one before.
