I get the advantages, but to me they seem offset by the high price and the disadvantages. To each his own.
At a minimum I'd suggest a PT as a first PM, with an SRM or Quarq later.
I guess you can have arguments on both sides. A PT is easily transferrable to multiple bike. A crank based PM makes it easy to switch between a training set of wheels and race day wheels. I mean if you have to choose between a nice carbon tubular race wheel or your clincher set to mount the PT on, which do you go with?
