If you have rotor 3d+ cranks I would suggest a Power2Max spider for them. Unless one of your bikes is bb90 you should be able to get a bb to fit it and swapping them between bikes is a 5min job.

Anything else I should be considering ? Garmin Vectors are better with pricing - £472 for left only vs £854 for l/r (and the upgrade kit for right at £412). However these tend to get a bad rep don't they ?
I know people have had issues with Vectors, particularly the first version, and my experience of them is pretty limited (one week's riding in Mallorca) but so far I've been very happy with mine. I've got them fitted in Ultegra 6800 pedal bodies and so far they've worked nicely. Installation is a bit of a faff in that it is best done with a torque wrench, but it's not that bad.

don't!!
I have vectors and even set up correctly they under read incrementally higher the more power you put through them vs. a watt bike, i'm pulling together proper data but at up to 200 its about 1% or less, then up to 300 it grows to about 5% and over 300 it gets up to 10% out, so they are probably ok for weekend warriors and indeed most club rides I avg about 200 or so, but for TT'ing I think the inaccuracy is too great!

I was considering a Powertap P1S (left only version)- easy enough to swap between my two bikes (Shimano 105 and Rotor 3d+ cranks) and also take on holiday for hire bikes, and in theory I could buy the right pedal at a later date.
Until I saw the price - £700 for left only vs £949 for both l/r
The crazy pricing for the P1S rules that out, and I'm not sure I want to drop £949 on a power meter for the dual l/r at the moment.
