I had a second PT hub on a carbon tubular but cracked the rim and didn't want to rebuild it at the time so I just sold it. Crank based is just easier to deal with that this point. Plus, when I did race with it in the past, I once had a flat early on in a race and had to change my rear wheel and lost my data. A bit silly, but also a bit annoying.
I also can't use my PT on my trainer, and as mentioned, since my trainer reads so low, I have to use my Quarq to have accurate power data.
