Reviving this thread as its time I got a PM.
Thoughts are that its either Garmin vector or Powertap P1s. Dual powertap is just too expensive for me at £900. Seems like a few of you have the Garmin Vectors and have got on ok with them. Do I really need two sided? its about £300 more which I could put towards some new shoes and a set of climbing wheels - or a bike box.
Any thoughts guys?

Who even does that?
One on each bike. They're becoming very cheap for what is in my opinion the best vfm and most reliable solutions. Only know folk with Vectors having run into a multitude of issues.
