Calfee was among the top on my list. My confusion when they stated that Manta was only for high end electronic and simply not for mech. I even asked for mech version but it was a no no. There are no best bikes. I don't think it is that easy to unworthy any way of build. I am sure i could ride a Calfee, or Guru, Argonaut or carbon and love it. I just fell in love with Paduano.. What matters is the there is no regrets. Had i more money i would probably try a another bike with Campy gearing just for the sake of having different bikes.
