The problem is that your l-r balance is almost certainly not constant or consistent. It typically varies with fatigue and also with cadence and power. So if you care about accuracy*, and you should if you are using a PM, then single sided makes little sense.
- Just a couple of percent out can make you think you are 10w up/down on your normal power, given that the gauges are typically only around +- 2% themselves that's not a good place to be.

I 'like' my Stages, paid £210 for it new and it works on all 4 bikes which makes up for the compromise of being L only. Do I prefer it to the Powertap fixed hub, no!
Unless you are getting a silly bargain price, spend a bit more another p2m, like the new NGeco. Will be getting one next.

Dare I ask for views and opinions on a single sided Stages G3 purchase (Campag)?
I have 2 * P2M units on other bikes (Type S for Campag and a track one on a Rotor crankset). Am just getting a bit bored swapping cranksets between two (geared, Campag 11) bikes.
I'm sure I'm in the vast majority of users with averagely balanced L-R so really don't need the extra metrics and stuff.
Are the G3 Stages with the latest firmware OK? Any experiences?
