Campag 2011 power torque

Would anyone who's actually worked on Powertorque with a gear puller say its worth selling on the 2011 set and buying a NOS 2010 ultratorque off ebay for a cost hit?

Not worth the swap if you're going to lose money, the problem with PT is not how it works when it works, but how hard it is to work on when it stops working, plus the very minor issue of the NDS bearing being a sliding fit on the axle, where one of the virtues of UT to engineering geeks is that the bearings are pressed onto the expensive part and slide into the cheap, easily replaced, cups. You'd need to do a lot of miles for that to actually be an issue in practice.
