Power Meters / Powermeters (SRM, Powertap, Quarq, Ergomo, Vector, Stages, power2max, P2M, 4iii, InPower, Cinch)

Does the hive mind have any views/experience on the pre-built Powertap wheels? I've decided the winter bike needs powah, given that I use it so much, and I'd rather have True Powah than use the Powercal all the time. I can't use my existing Powertap wheelset as the winter bike runs Campag.

Just buy the hub and get a good wheelbuilder to sort the rest.
