Carbon Cranks




what do you's think of these carbon cranks? iv heard stories of carbon breaking is this true or is that with the older carbon when carbon was still developing

these are aparently US $450 cheaper than campag?
I will ONLY have these carbon cranks on my bike, ONLY after I have seen Chippo or Zabel or
Stuey or McEwen using and winning SAFELY . ::)
Nice, has anyone here considered buying a Titanium crank 8)? They are just as light and are very, very strong.
