Thanks Andrew, DCrainmaker is one of those that you can miss, lots of reviews pretty much about everything. I’ve had a good chat with some of the guys last Sat after the ride and now I’m more convinced that right/left split is not really necessary at least for my situation, so The way forward for me is either Garmin vector 2S or powertap with more weight given to Garmin.
What is the one that your waiting for?
Cheers,
Nirvan
